Sphenocorona information

In geometry, the sphenocorona is a Johnson solid with 12 equilateral triangles and 2 squares as its faces. The sphenocorona was named by Johnson (1966)...

sphenocorona is the Johnson solid that can be constructed by attaching an equilateral square pyramid to one of the square faces of the sphenocorona....
