I have the same issue. Please fix it :)

I do not understand the kata at all. There is quite strange explanation what to do.

[Haskell]

Is there any test case for haskell? I spent a lot of time solving this kata (and I did it). But I was disapointed when found out that tests are missed.

(Haskell)
I've written the function, tests were ok . Then I push submit and got very strange error :

tmp/haskell115614-19-19p8kzn/Codewars/Kata/Permutations/Test.hs:18:7:
No instance for (Show a0) arising from a use of forAll' The type variable a0' is ambiguous
....
a lot of output.
