%N Numbers whose base-10 digits d(m), d(m-1),..., d(0) have m=0 or else d(i) = d(i+1) for some i in {0,1,...,m-1}.
%C These numbers comprise the complement of the set of numbers in the union of A297146 and A297147.
%C Differs from A044821 first for 1001, which is in this sequence but not in A044821. - _R. J. Mathar_, Jan 17 2018
