COMMENTS

Equivalently, the number of polyhexes with n-k cells and k distinguished vertices.
This sequence counts "free" polyforms where holes are allowed. This means that two polyforms are considered the same if one is a rigid transformation (translation, rotation, reflection or glide reflection) of the other.
