There are 35 distinct hexomino patterns. A hexomino is formed by connecting six squares edge-to-edge, and these patterns can be flipped and rotated, but the 35 unique configurations account for all such transformations. Hexominoes are a type of polyomino, and they can be used in various mathematical and recreational contexts, including tiling and puzzle design.
