Comment	Post #288398	Ah I think you are misunderstanding, the you are dividing it into k-polyominos. There are no additional requirements on these polyominos. So ```text X XX XXXXX ``` can be subdivided into a T-tetramino and a O-tetramino. It doesn't matter that these are not the same 4-polyomino. You just ... (more)	—	almost 2 years ago
Comment	Post #288398	I'm not sure what you mean. There's no canonical way to select an enantiomorph, so yes it is possible for to mirror images to be inputs, if that's what you are asking. No part of this question involves determining if two polyominos are equal so it shouldn't matter whether you consider chiral pairs t... (more)	—	almost 2 years ago
Comment	Post #288398	Input a polyomino is intended to be flexible. I'd be certainly be willing to let you take a list of coordinates, and I believe if taking a list it is acceptable to also take its length. So that would be one way to take the input with the number of squares. (more)	—	almost 2 years ago

Question	—	Determine if a polyomino is "prime" An $n$-polyomino is a connected subset of the square tiling consisting of $n$ squares. We will not require that polyominos be simply connected, that is they can have holes. We will say a $n$-polyomino is prime if it cannot be disected into disjoint $k$-polyominos for any 1<$k$<$n$. For example th... (more)	—	almost 2 years ago
