Re: Polyominoes

I built another rectangle I haven't seen anywhere before, again using one of each of the heptominoes: a 20x38 with 4 holes (placed symmetrically). 20x38.png This ended up taking an entire evening of playing around with my little homemade heptomino set. I had attempted this rectangle ages ago, and ha...

Polyominoes

Anyone else on here have an interest in polyominoes or other polyforms (outside of a cellular-automata context, I suppose)? I've been playing on with various sets a fair bit recently, pentominoes and hexominoes mainly, just constructing (or attempting to construct) rectangles and other shapes with t...

Re: Random posts

I somewhere saw a "3c partial, obviously not extensible". It was small. But I forgot where it was.

Some of the oscillator list pages for 2x2 symmetries are not sorting the objects by number of occurrences, e.g. https://catagolue.appspot.com/census/b36s125/D8_4/xp4

Re: 2x2

The p6 (and it's smaller variant ) both occur naturally; I (possibly re-)discovered them back in 2011, but they could have been known before that. I've got the p8 saved as well, but no idea who found it and when. The P4 and P5 are definitely new though. I've stuck an updated collection in the first ...
