it's counter intuitive, like a paradox, a potato paradox maybe "wink wink"

Easy code wise but mentally weirdly hard!

Not a kata issue, you have read the description wrong.

For Rust:

I just tried and the test cases fails when the red knight starts in odd numbers. The assert always point to even results, which is incompatible with odd starts. Reviewing the test cases, they can work good if substract one when odd (for test cases).

Python, some others:

• argument names should be lowercase

Note to self: ANALYZE THE TEST CASES!!!!!

Java: a masterclass on how to not write a KATA.

nah it's indeed a 7kyu the description needs better.
by greatest it means a group of 5 numbers that as a number is higher than the other groups

fixed and updated to chai+assert

This kata is subtle genius.

I don't think this is a troll kata, It just made me realize I am not as observant as I thought.

Google what is a Wilson prime number before you get mad at the kata like me.

This could be considered as a 7kyu
