Gyroelongated Square Cupola

In geometry, the gyroelongated square cupola is one of the Johnson solids (J23). As the name suggests, it can be constructed by gyroelongating a square cupola (J4) by attaching an octagonal antiprism to its base. It can also be seen as a gyroelongated square bicupola (J45) with one square bicupola removed.

The 92 Johnson solids were named and described by Norman Johnson in 1966.

Famous quotes containing the word square:

    A man who is good enough to shed his blood for his country is good enough to be given a square deal afterwards. More than that no man is entitled to, and less than that no man shall have.
    Theodore Roosevelt (1858–1919)
