Polyabolo

From Wikipedia, the free encyclopedia

In recreational mathematics, a polyabolo (also known as polytan) is a polyform with a right isosceles triangle as the base form.

The name is a back formation from 'diabolo' although the shape formed by joining two triangles at just one vertex is not a proper polyabolo.

The number of polyaboloes of order 1, 2, 3, … is 1, 3, 4, 14, 30, 107, … (sequence A006074 in OEIS).
