%N A062279 Smallest multiple k*n of n which is a palindrome or becomes a palindrome 
               when 0's are added on the left (e.g. 10 becomes 010 which is a palindrome).
%C A062279 Every positive integer is a factor of a palindrome, unless it is a multiple 
               of 10 (D. G. Radcliffe, see Links).

               multipliers to make a number palindromic</a>.
%e A062279 a(13) = 494 is the smallest multiple of 13 which is a palindrome.
