[seqfan] A sequence of sequence-generating matrices

[Russell Walsmith]

Exploring different numerical sequences* generated by a certain 3 x 3
matrix, I found it to be part of an n x n family with a similar, though
increasingly complex, form. I've discovered six entries in this sequence of
matrices so far... does anyone see where it goes from here...?
