%N Palindromes with distinct prime signatures that occur naturally. Smallest palindrome with a prime signature of A025487(n), or 0 if no such number exists.
%C Zero values are not proved. I have searched for a(33) (p^6*q^2) and a(42) (p^7*q^2) up to 10^20 and for the other six zeros (p^5 through p^10) up to 10^40. - _David Wasserman_, Feb 17 2005
%e a(7) = 14641 because A083435(7) = 16, the fourth power of a prime and 14641 is the smallest palindrome that is the fourth power of a prime.
%Y Cf. A025487.
