%N A000110 / (1,2,3,...): (convolved with (1,2,3,...) = Bell numbers).
%C This is the sequence which must be convolved with (1,2,3,...), offset 0, to generate the Bell numbers starting (1, 2, 5, 15, 52, ...) offset 1;
%C equivalent to row sums of triangle A154109 = (1, 2, 5, 15, 52, ...).
%C A variant of A011965. - _R. J. Mathar_, Jan 07 2009
%F A000110 / (1,2,3,...); where A000110 (the Bell numbers) begins with offset 1: (1, 2, 5, 15, 52, 203, 877, ...).
%F G.f.: (A000110(x)-1)*(x-1)^2, where A000110(x) is the g.f. of the Bell numbers. - _R. J. Mathar_, Nov 27 2018
