The table gives information about some of the human body parts.

The names of the body parts are all coded and the count of those body parts present in a normal human are given.

Coded body part Count
AH 1
MN 2
AIT 1
A 1
BIMU 2
AHIIP 10
??? 206

What codeword (of length 3) will complete the table?

    $\begingroup$ @Vesper Probably there is not enough data to decode as you said. But if I add even a tiny detail, many of them will solve it within minutes. I am interested to see if someone will decode it with the existing information. You can call it an experiment. $\endgroup$ Jul 5, 2023 at 13:08

Since there are 206 bones (and not a lot else in that exact quantity) in the typical adult human body, it's no secret that we seek a 3-letter code for the word BONE. This would be:

ALN

Why? Because the method used to encode body parts in this puzzle involves...

...finding the name of a country (in English) that contains the letters of the body part in question (not necessarily in order), removing those letters, and then alphabetising what remains!

For the examples given:

AH (1) = BRAIN from B(ah)RAIN
MN (2) = EYE from YE(m)E(n)
AIT (1) = NOSE from ES(t)ON(ia)
A (1) = CHIN from CHIN(a)
BIMU (2) = LEG from (b)ELG(ium)
AHIIP (10) = TOE from ET(hi)O(pia)

So to get BONE we need:

ALN (206) = BONE from (l)EB(a)NO(n)

  • $\begingroup$ Nicely done! Out of curiosity, can I ask how did you decode? $\endgroup$ Jul 7, 2023 at 1:10

    $\begingroup$ But then there's no one-to-one correspondence for encoding. The word encoded A could've been encoded EEEILNSTT instead, for example. $\endgroup$

  • $\begingroup$ @msh210 I'm not disputing that. I thought about it too which is why I specified the length of the required codeword in the question. I appreciate your comment. Sometimes I am deliberately interested in knowing how much information should be revealed in the puzzle which was why I shared this question. $\endgroup$ Jul 7, 2023 at 4:18
  • $\begingroup$ @msh210 Perhaps we should consider just the shortest candidates? $\endgroup$

    $\begingroup$ @msh210 Having said that, the fifth one could equally be encoded AAIR, which is the same length... But all things considered, I think it's still valid to think of this puzzle as a case of 'these body parts have been obfuscated in some way - can you work out what I did, and do similarly for this example...?' rather than necessarily expecting it to be a formal 1-1 reversible cipher system. The body parts just can and have been 'encoded' in this pattern-like way that we need to spot. This won't be the next big player in cyber-security hashing! :) $\endgroup$
