%N Numbers divisible by a square and which have the same property if any number of rightmost digits is deleted.
%C This regards the interplay between an endomorphism E on the set N and a number property P. In this case, E(n)=floor(n/10) for n >=10 and E(n)=n otherwise, and the property P is "moebius(n)=0". The goal is to find the numbers whose consecutive images under E all have the property P.
