%N The first nfold intrinsically 5palindrome (represented in base ten).
%C The fourth term, which is first 5palindromic in base 91, is almost a concatenation of baseten 5palindromes.
%C A217146 gives the sequence of values 5palindromic in at least 4 bases. The search there indicates a fifth term here has first base of 5palindromicity above 200.  _James G. Merickel_ Oct 19 2012
