%N A097060 Revrepfigits (reverse replicating Fibonacci-like digits): Numbers n such 
               that their reversal occurs in a sequence generated by starting with 
               the n digits of a number and then continuing the sequence with a 
               number that is the sum of the previous n terms.
%C A097060 Numbers ending in zero are not permitted since the zeros are dropped 
               upon reversal. However, terms with internal zeros such as 90711 are 
               permitted. Conjectures: 1. Sequence is infinite. 2. Revrepfigits 
               are more rare than repfigits.
%C A097060 There are no 12-digit revrepfigits.
