%N Intrinsic 9-palindromes: n is an intrinsic k-palindrome if it is a k-digit palindrome in some base.

%C All numbers are intrinsic 1- and (for n>2) 2-palindromes, almost all numbers are intrinsic 3-palindromes and very few numbers are intrinsic k-palindromes for k >= 4. - _Franklin T. Adams-Watters_, Jul 29 2011
