%N Triangle read by rows: n-th row is the lexicographically earliest arithmetic progression of n numbers all having the same prime signature.
%C Presumably this triangle will differ from that in A130791 after some point. - _N. J. A. Sloane_, Sep 22 2007
%C Apart from the initial term, this sequence coincides with A130791 for at least the first 210 rows. - _David W. Wilson_, Sep 22 2007
