1 Answer 1


This is just

a sentence in the Atbash cipher - the cipher where A is swapped with Z, B with Y, and so on.

The title is Reversed Alphabet Puzzle.

The text of the question is:
Every letter has been replaced with the corresponding letter in the reversed alphabet.
Is the number of letters in the above sentence prime or composite?
If I've counted correctly, there are 73 letters in that sentence, which is a prime number.
