Re: [math-fun] A Permutation Cipher Text

      Another similar scheme produces the cipherimage:

with a decryption key:

"hxxstvjhdcvrcmhuhphufxhdshirjpgjblcgrovfuhisoweubrviplbcpulvflwpdlgjjhidhktchvtpjlhwtfstnkdfowss"

from a permutation space of size ~10^132, as in:

https://0x0.st/zxaI.pdf .

Any thoughts?

Easy to brute force if you get the gist of the permutation
scheme but looks difficult to reverse engineer otherwise.
Codebreaking algorithms?
