These are conforming polydrafters as in A056842, as defined by Ed Pegg. They do not include extended polydrafters. See the Logelium link.

A polykagome is a set of adjacent cells on the trihexagonal grid.

A polyming is a generalized polyiamond whose cells may be joined at corners as well as at edges. I introduced the term in 2010. In A319324 and elsewhere, David Bevan calls these shapes "polyglasses." In A239658, Abe Wits and Ragnar Groot Koerkamp call them simply "triangular polyplets."

A polyfett [polifetto] is a generalized polyabolo [polytan]. It is formed by joining isosceles right triangles on the quadrille grid along edges and at corners.

A polyfett is a generalized polyabolo (or polytan). Its cells are equal isosceles right triangles on the quadrille grid, which may be joined along equal edges or at vertices.

Polyfetts are to polyaboloes what polyplets (or polykings) are to polyominoes.

A perforated polyomino is a polyomino in which every cell has at least one even coordinate.

This sequence also gives the number of Ul Qoma Polycubes with n cells. An Ul Qoma Polycube is a polycube whose cells each have two or more odd coordinates.

This sequence also gives the number of Ul Qoma Polycubes with n cells. An Ul Qoma polycube is a polycube whose cells each have two or more odd coordinates.

An extended polydrafter is a plane figure formed by joining congruent 30-60-90 triangles along edges and half hypotenuses, without the requirement for proper polydrafters that the cells lie on the polyiamond (triangle) grid.
