%N Integers whose digits, together with a single supplementary digit, cannot be reordered to form a base-10 palindrome number.

%C This is the complement of A303502.

%C Starts with the 648 terms of A031962. - _Georg Fischer_, Oct 08 2018

%e a(1) = 102 together with a single 0 can form 1002, 1020, 1200, 2001, 2010 and 2100, but none of these are palindromes;

%e a(1) = 102 together with a single 1 can form 1012, 1021, 1102, 1120, 1201, 1210, 2011, 2101 and 2110, but none of these are palindromes;
