%N Smallest palindromic multiple of (n with trailing 0's omitted, A004151) using only nonzero digits of n; all digits must appear; or 0 if no such number exists.

%C If one generates all palindromes using all the digits of n with k digits where k starts with the number of digits of n and increases k until one finds a multiple of n, one finds such palindromic multiples much faster than looking for palindromes among the multiples of n. - _W. Edwin Clark_
