%N A144799 Integers having ideal digital mean up to base 4.
%C A144799 Subset of A031443 and A144798.
%C A144799 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 <= 4.
