%N A144800 Integers having ideal digital mean up to base 5.
%C A144800 Subset of A031443, A144798 and A144799.
%C A144800 These numbers have digital mean dm(b, n) = (Sum_{i=1..d} 2*d_i - (b-1)) / (2*d) = 0, where d is the number of digits in the base b representation of n and d_i the individual digits, for 2 <= b <= 5.
