Hi all fans,
A new index of sequences related to polyforms (polyominoes, polyhexes, ...) has been created: https://oeis.org/wiki/Polyform-index
It would be useful if, over time, contributors could keep the index up to date by adding new sequences. Any corrections to the index or suggestions for improvement would also be welcome. (In the short term, I can make corrections if you write to me.)
Caveat: variations of sequence names are not reflected automatically, and so these too should be performed manually to keep the index up to date.

You may be interested in
https://oeis.org/wiki/User:Joseph_Myers/Poly-T-tiles which is my index of
sequences for poly-T-tiles for an isohedral tiling T.

You may be interested in

You may also be interested in my blog posts with tables—
https://quuxplusone.github.io/blog/2022/12/08/polyomino-snakes/ (snake polycubes and polyominoes of various kinds)
https://quuxplusone.github.io/blog/2025/08/23/polybars/ (polybars of order 3 and higher, where "polybars of order 2" are the polydominoes)
Most of the rows/columns of these tables aren't in OEIS.

Thanks Joseph. I have checked and I think all the sequences in your table are in the new index. However, it might be interesting to include a link to your table in one of the new index pages.

Thanks Arthur. My main aim now is to index existing OEIS polyform sequences, not introduce new ones. OTH, if you publish new sequences, I will be only too pleased to index them if you don't do it yourself.
