The 5^th prime multiplied by 5 is a palindrome (5*11=55).
Find additional numbers n such that when multiplied by the n^th prime create a palindrome.
Exclude the trivial cases of n=1 and n=2.

I think the solution could be found to this puzzle manually by finding a general formula for the nth palindrome.But I am not sure about this.
