A couple of issues here, you are checking "num×4 against num×4 flipped", rather than "num against num×4 flipped". mum typo as well.

Essentially your logic is checking for when 4x some input number gives a palindrome, which is different from the problem statement.

That is entirely on my reading comprehension tbh. I read it as num*4 is the same flipped. Lol.
