727. The smallest palindromic number greater than 500 independent of primicity is 505.
343 is the palindromic and cube number.7*7*7=3437 is being times three times by itself to get this palindromic and cube number.Also 1331 is a palindromic and cube number.11*11*11=133111 is being times three times by itself to get this palindromic and cube number.
Oh, dude, 1331 is not a prime number. It's like the opposite of a prime number, you know? It's actually 11 raised to the power of 3, which makes it a perfect cube. So, yeah, it's not a prime number, but hey, at least it's special in its own nerdy math way.
A palindromic number is a number that is read the same forwards and backwards.
It is not a prime.
