# Find the word with the highest normalized product of letter-prime values where A=2, B=3, C=5, ..., Z=101

Which word has the highest normalized score according to the following:

• Assign each individual letter A..Z of an (English) word a value corresponding to the n'th prime (see table below).
• Take the product of its letter values.
• Normalization: Take the log10 of that product, and divide by the wordlength.
• (See Python example code below)
• Please state the wordlength along with its score

Examples:

• SYZYGY = 1.83686.. (6 letters)
• WOW = 1.83675.. (3 letters)
• SYZYGIUM = 1.73403.. (8 letters)
• WOODWORKING = 1.56381.. (11 letters)

(The normalization is to prefer everyday English words over IUPAC chemical names or 'Pneumonoultramicroscopicsilicovolcanoconiosis').

Letter values A:2 B:3 C:5 D:7 E:11 F:13 G:17 H:19 I:23 J:29 K:31 L:37 M:41 N:43 O:47 P:53 Q:59 R:61 S:67 T:71 U:73 V:79 W:83 X:89 Y:97 Z:101

Some Python example code:

import string
from math import log10

primes = { letter_prime[0]:letter_prime[1] for letter_prime in zip(string.ascii_uppercase, [2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101])}
{'A': 2, 'B': 3, 'C': 5, 'D': 7, 'E': 11, 'F': 13, 'G': 17, 'H': 19, 'I': 23, 'J': 29, 'K': 31, 'L': 37, 'M': 41, 'N': 43, 'O': 47, 'P': 53, 'Q': 59, 'R': 61, 'S': 67, 'T': 71, 'U': 73, 'V': 79, 'W': 83, 'X': 89, 'Y': 97, 'Z': 101}

def letter_prime_score(word):
prod = 1
for letter in word:
prod *= primes[letter]
return log10(prod) / len(word)

letter_prime_score('SYZYGY')
1.8368600501100796

letter_prime_score('WOW')
1.8367513475626218

letter_prime_score('SYZYGIUM')
1.734027889906502

letter_prime_score('WOODWORKING')
1.5638076854903682

• It depends on you want a longest word contest or not; I feel that a ridiculously long word should win the contest every time, even if a word like zyzzyva = $101^3 \times 97^2 \times 79 \times 2$ is oodles more efficient in generating a high score on a per letter basis. Commented Aug 28, 2018 at 20:07
• @El-Guest: right, totally. Let's normalize its log by wordlength.

• smci, to be honest, this kind of favours a shortest word contest now haha ;P Commented Aug 28, 2018 at 20:26
• @El-Guest: yeah, don't know how to avoid that unless you can suggest a better normalization. How about trying to find the highest 3-letter word, 4-leter, etc.

• Yeah, that might be the best way to do things! If you go from 1 to as high as you want, I can supply "I" and "OZ" immediately haha Commented Aug 28, 2018 at 20:32

The word that I got was ZYZZYVA, a valid Scrabble word, and a type of snouted beetle, most famous for being the final word in the dictionary. The total points are $101^3 \times 97^2 \times 79 \times 2$, which is equal to $1.5316681 \times 10^{12}$. If we normalize this by taking the logarithm and dividing by the number of letters in the word, we get $\frac{\log 1.5316681 \times 10^{12}}{7} \approx 1.74073781098$.

In comparison, SYZYGIUM results in $\frac{\log 74511467904889}{8} \approx 1.73402788991$.

WOODWORKING results in $\frac{\log 159178548575947607}{11} \approx 1.56380768549$.

PNEUMONOULTRAMICROSCOPICSILICOVOLCANOCONIOSIS results in $\frac{\log 2.09 \times 10^{65}}{45} \approx 1.45155880636$.

Update On the other hand, my first suggestion punished long words as much as it favoured small words. Therefore:

1 letter: I results in $\frac{\log 23}{1} \approx 1.36172783602$.
2 letter: XU results in $\frac{\log 73 \times 89}{2} \approx 1.90635643338$.
Note: This word found by @Herb Wolfe! Go upvote their answer!! :D
3 letter: ZZZ results in $\frac{\log 1030301}{3} \approx 2.00432137378$.
Note: Check the link for ZZZ, it's in the Merriam Scrabble Dictionary!
4 letter: ZIZZ results in $\frac{\log 23696923}{4} \approx 1.84367298934$.
Note: Apparently ZIZZ is in the Merrriam Scrabble Dictionary too!
5 letter: ZZYZX results in $\frac{\log 8694710139}{5} \approx 1.98785102165$.
6 letter: ZYZZYX results in $\frac{\log 862775087701}{6} \approx 1.98931626609$.
Note: This word found by @peaceoutside! Go upvote their answer!! :D
7 letter: ZYZZYVA results in $\frac{\log 1.5316681 \times 10^{12}}{7} \approx 1.74073781098$.
8 letter: ZYZZYZUS results in $\frac{\log 4.7887992 \times 10^{15}}{8} \approx 1.96002832831$.

• @smci, how about these others? Commented Aug 28, 2018 at 20:37
• Huh, I missed ZZZ in the Merriam Scrabble Dictionary.

• At 10-letters I see TOPSYTURVY for 1.8444788482629637 (beating ZIZZ!) Commented Aug 28, 2018 at 21:42
• @smci - I have posted a result of a Python script run across a list of words acquired from the internet, it has TOPSYTURVY as the entry for length 10 :) Commented Aug 29, 2018 at 10:03

Zyzzyx

is 1.989316266087555

It's a genus of sand wasp, as well as a road, an album title, a film title, a place in California and a few other things.

• I guess that's unbeatable. Presumed winner for 6-letter words

Using the list of words in the souptonuts project and a little Python I get these (word length, score, word) tuples - the first two seem dubious as "English words", but I include them since I'm using that list:

• it takes the list of words as input -- that needs changing to access and parse a file with the words in if you want to use it with a huge word list like I did.

For two letter words:

Xu, a monetary unit of Viet Nam scores 1.90635...

For three letter words, I came with:

Zuz, an ancient Hebrew silver coin scores 1.95732...

Zax, a tool for cutting roof slates, however it only scores 1.41824...

For a four letter word:

Zizz, to make a buzzing sound. Score: 1.84367

• It's scary how much of an effect A has on the score! Commented Aug 28, 2018 at 20:40
• Nice 2 letter find! Commented Aug 28, 2018 at 21:04

So far:

• 4 letters: ZIZZ = 1.84367..
• 6 letters: SYZYGY = 1.83686..
• 3 letters: WOW = 1.83675..
• 5 letters: PROPS = 1.74641..
• 4 letters: ZIPS = 1.7291
• 5 letters: WHUPS = 1.72230..
• 8 letters: PROSPERS = 1.67311..
• 7 letters: PROSPER = 1.65125..
• 6 letters: SPORES = 1.64587..
• 7 letters: ZIPPERS = 1.6382..
• 8 letters: PAROXYSM = 1.60722..

(We added normalization to exclude freaks like PNEUMONOULTRAMICROSCOPICSILICOVOLCANOCONIOSIS which scored a ridiculous 2.09e+65 without normalization, but only 1.45155 after).

• PAROXYSM is 8 letters, and is beaten by both SYZYGIUM and ZYZZYZUS I think Commented Aug 28, 2018 at 20:46
