Their symmetry group has four elements. It is the dihedral group of order 2, also known as the Klein four-group. If reflections of a hexomino are considered distinct, as they are with one-sided hexominoes, then the first and fourth categories above would each double in size, resulting in an extra 25 hexominoes for a total of 60.

Jan 7, 2024 · The hexominoes (order-6 polyominoes) are a set of geometric shapes made up of six squares joined edge-to-edge in every possible shape. Discounting rotations and reflections, there are 35 shapes as shown above.

The hexominoes are, of course, polyominoes made from six squares. There are exactly 35 of them, and here they are (picture from Wikipedia):

Apr 8, 2025 · A hexomino is a 6-polyomino. There are 35 free hexominoes (illustrated above), 60 one-sided hexominoes, and 216 fixed hexominoes.

The six red hexominoes have an axis of mirror symmetry parallel to the gridlines. Their symmetry group has two elements, the identity and a reflection in a line parallel to the sides of the squares.

Mar 29, 2025 · There are 35 distinct hexominoes, the majority of which behave uninterestingly. The most interesting and well-known examples are century, line-of-six spark, stairstep hexomino, table, toad, Pre-beehive and Z-hexomino.

Jan 14, 2025 · HexominoES (or 6-omino) is a polyomino of order 6; that is, a polygon in the plane made of 6 equal-sized squares connected edge to edge.

Jul 20, 2022 · In this lesson, students will engage in a hands-on learning activity centered around a geometric construct called a hexomino. Similar to the more familiar domino (with two squares fused together on a side), a hexomino consists of six squares fused together.

A hexomino is a figure in a plane formed by six squares such that any two squares have a side in common. Here are two examples of hexominoes: . Your task is to find all possible forms of hexominoes. You can draw the hexominoes using pencil and paper or build them using linking cubes or another manipulative. 1.

Below are a number of constructions made with full set of 35 hexominoes. The 'rhombus' shape at the bottom is by David Bird and the one at the top right is by W. Stead.
