A polyiamond (also polyamond or simply iamond, or sometimes triangular polyomino[1]) is a polyform whose base form is an equilateral triangle.

4 days ago · A polyiamond is a polyform consisting of a collection of equal-sized equilateral triangles arranged with coincident sides. Polyiamonds are sometimes simply known as iamonds.

Jan 8, 2025 · (geometry) A polyform made by joining one or more equilateral triangles edge to edge in various arrangements. Every polyiamond corresponds to a polyhex, Some authors also call the diamond (rhombus with a 60° angle) a calisson after the French sweet of similar shape.

A generalization of the Polyominoes using a collection of equal-sized Equilateral Triangles (instead of Squares) arranged with coincident sides. Polyiamonds are sometimes simply known as Iamonds.

In the diagram below the three figures on the left are polyiamonds but the two on the right are not. A list of the numbers of polyiamonds for a given value of n is available at Sloane's On-Line Encyclopedia of Integer Sequences which also has the numbers of …

Polyiamonds are plane geometric figures constructed by pasting together equilateral triangles edge-to-edge.

Polyiamonds are polyforms based on the equilateral triangle ( ), or the triangular grid. The number of polyiamonds of size N: 1, 1, 1, 3, 4, ... 1, 1, 1, 4, 6, ... 1, 1, 1, 2, 3, ... There is a single monoiamond. There is a single diamond. There is only one triamond. There are three tetraiamonds. They are referred to as I, C, and T.

A polyiamond is a polyform whose base form is an equilateral triangle. The word polyiamond is a back-formation from diamond, because this word is often used to describe the shape of a pair of equilateral triangles placed base to base, and the initial "di-" …

Sep 7, 2020 · Polyiamonds are the shapes made by connecting equilateral triangles edge-to-edge. What sort of polyiamond you've got depends on how many triangles it contains. If it's just the one triangle, you've got what could be called a moniamond or mono-iamond, but is probably better off just being called an equilateral triangle, for everyone's sake.

A polyiamond (also polyamond or simply iamond) is a polyform in which the base form is an equilateral triangle. The word polyiamond is a back-formation from diamond, because this word is often used to describe the shape of a pair of equilateral triangles placed base …
