Anyone may wish to find 
the first term 
that isn't multiple of 5 ?


PS Note that I added 1 as the first term,
so we look for term(s) > 1. 

%S A129066 1 (* added by me *), 5,25,125,625,3125,15625,75025,78125,375125,390625,1875625,1953125,9378125,
%T A129066 9765625,46890625,48828125
%N A129066 Numbers n such that n divides Fibonacci(n) with multiples of 12 excluded.
%C A129066 a(n) includes all terms of A023172(n) with terms 12*A072378(n) excluded.
