This terminology is wrong;
a^-1is the modular multiplicative inverse ofain respect ofn, not modular multiplicative inverse ofa mod n.edited
Looks like a duplicate to me.
This one is easier. The other one has a broader alphabet, including greek letters. They may still be considered duplicates though. Edit: that other kata requires some serious rework on all levels (tests, error feedback, spec).
Did we somehow reach the point where having a different input alphabet makes the same kata not duplicate?
Not to my knowledge, no. I stated the difference between both kata's. Let the community decide uniqueness.
The description is fuzzy about the meaning of
min the modular multiplicatie inverse. It appears(x-b)ism, but it is not. I suggest to reword this part, to explain whatmis.description has been reworded 'm' was a typo
a^−1is the modular multiplicative inverse of a mod n (a number 'z' such that a.z≡1 mod n).This comment has been hidden.

ok
the decryption function is missing a colon in the solution setup
resolved
Hi,
The setup is ok, but asking only for encryption makes your kata too close to any other basic cipher kata. It has been done to death already and brings nothing new. The task as a stand alone is doomed to sit in beta, imo. Unpublishing so that you can change your mind and add decryption to it. Maybe it can make a difference (note that some users might even disagree about that).
cheers
decryption has also been added
