As the name suggests, it can be constructed by gyroelongating a pentagonal rotunda ( " J " 6 ) by attaching a decagonal antiprism to its base.

As the name suggests, it can be constructed by gyroelongating a pentagonal cupola ( " J " 5 ) by attaching a decagonal antiprism to its base.

This is called " gyroelongation ", which means that an antiprism is joined to the base of a solid, or between the bases of more than one solid.
44.
The snub disphenoid ( " J " 84 ) is another deltahedron, constructed by replacing the two squares of a square antiprism by pairs of equilateral triangles.
45.
The only nonconvex uniform 4-dimensional antiprism analogue uses pentagrammic crossed-antiprisms instead of pentagonal antiprisms, and is called the " pentagrammic double antiprismoid ".
46.
If " p / q " d " 3 / 2 no uniform antiprism can exist, as its vertex figure would have to violate the triangle inequality.

None of the prisms is optimal for packing . ( The 2-antiprism is the tetrahedron . ) Tamfang 09 : 00, 2 September 2007 ( UTC)

In this respect, it can be seen as a " capped " square antiprism ( a square antiprism with a pyramid erected on one of the square faces ).

In geometry, the "'gyroelongated pyramids "'( also called augmented antiprisms ) are an infinite set of pyramid to an n-gonal antiprism.
