Two Types of Hexagonal Polyominoes Counted by Area and Number of Columns
Two Types of Hexagonal Polyominoes Counted by Area and Number of Columns
A column-convex polyomino is a polyomino in which every column is free of gaps. A level-one column-subconvex polyomino is a polyomino in which every column either has no gaps or has exactly one gap that consists of exactly one cell. In this Demonstration examples of both types are constructed using hexagonal cells.
