%N Palindromes with exactly 3 distinct prime factors.
%C The terms must have only three distinct prime factors even when counted with multiplicity. For example, 252 is not a term even though (1) it is a palindrome and (2) only three distinct primes occur when it is factored, because 252 = 2*2*3*3*7.  _Harvey P. Dale_, Aug 29 2016
