%N Integers k such that the digits of k together with a single supplementary digit can be reordered to form a base-10 palindrome.

%e a(1) = 1 together with a single 1 forms 11;
%e a(2) = 2 together with a single 2 forms 22;
%e a(3) = 3 together with a single 3 forms 33;
%e ...
%e a(101) = 101 together with a single 0 forms 1001;
%e 102 is not in the sequence as no palindrome can be formed from the set [0,1,2,d], d being any single digit;
%e a(354) = 1002 is in the sequence as 1002 together with a single 1 forms 10201;
%e etc.
%Y Cf. A002113 (palindromes in base 10), A303504 (complement to this sequence).
