I'm not sure if it's just permutations. "kudtce" could be "tucked", but
"erontuf"?
Anyway, I would personally permute only consonants - if the vowels are
out of order, the brain can often fill in the blanks pretty easily.
Also, it would be great to leverage ispell to exclude non-words from the
list of permutations - unfortunately, I don't know how to do it
(`ispell-word' looks pretty magical to me, at least after ~10 minutes of
looking - maybe if I had more time...)
But this made me think - one could write a simple game (a bit like M-x
decipher) to help decipher "permutation-based secret messages". Looks
like a fun project.
Also, you don't have to list all the permutations to _count_ them -
Emacs can actually compute factorials:
(calc-eval "fact(5)") => "120"
(calc-eval "fact(10)") => "3628800"
Best,
