Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 59th year, we have over 358,000 sequences, and we’ve crossed 10,300 citations (which often say “discovered thanks to the OEIS”).

COMMENTS

Encodes which row/column patterns may be adjacent in 01-matrices where no two 0 elements may be adjacent. Contains many interesting recursive patterns such as Fibonacci-sized blocks of 0's along main diagonal.

LINKS

Table of n, a(n) for n=0..104.

EXAMPLE

T(3,4) = 0 because F(3) AND F(4) = 4 AND 5 = 1, which is nonzero.
