%N A110811 Perfect powers whose digit reversal is also a perfect power, ( not necessarily 
               with the same index, but the index > 1.
%C A110811 All palindromic perfect powers are trivial members, but there are infinitely 
               many nontrivial members.
%e A110811 12^2 =144, digit reversal of 144 is 441= 21^2. 12769=113^2, reversal(12769) 
               = 96721 = 311^2.
%Y A110811 This is a subset of A115656 and also a subset of A001597. See also A118895 
               to include terms with trailing zeros.
