Once we hit n = 4, we're in full swing: there's finally specimens for all seven combinations of pieces, and ten total unique solutions controlling for symmetry. I have to stop and pay attention to work for a bit, but one of the things I'm excited to fiddle with more is looking at where genuinely new non-decomposable patterns show up (like the sixth one down on the left in this image) where it's not just a concatenation of previously attested smaller specimens.
