Nice interactions between the palindromes and anti-knight constraint.
The palindrome between R9C3 and R8C4 that breaks rotational symmetry is not necessary for a unique solve. I didn't use it.

Response from Eric: Thank you DiMono. Congratulations on the solve. Good eye spotting the one mini palindrome that broke the symmetry. Interesting that you found a way to solve it without that palindrome. I'll probably leave the puzzle as is since so many have already solved it, but I will give it a go myself to see if I can do it without that palindrome. Thanks for letting me know. I always try to minimize clues and keep symmetry when possible.

Great puzzle! Very satisfying from start to finish, and it just felt like a quintessential Rathbun puzzle, and I mean that as an upmost compliment. Thanks Eric!
