%N Non-palindromic numbers which are divisible by their reversal.

%C A004086(a(n)) = A027751(a(n),k) for some k: 1 <= k < A001221(n); A031877 contains all terms not ending with zero. - _Reinhard Zumkeller_, Jul 15 2013

%H Reinhard Zumkeller, <a href="/A118959/b118959.txt">Table of n, a(n) for n = 1..10000</a>

%e 510 is in the sequence because 510 is a non-palindromic number divisible by its reversal 15.
