[seqfan] Re: Filling squares and triangles (with digits)

[L. Edson Jeffery]

NJAS>I think we should use both styles for both sequences, so we will have
four new sequences in all.

Also, Eric's squares or triangles could be filled with 0,1,2,..., starting
the filling process with 0 instead of 1. In this case, the 4X4 square could
then be filled but not the 5X5 one. What do these sequences look like?
