Its Schlegel diagram can be formed as a square pyramid with a single vertex inside it connected by edges to all five pyramid corners.

Each removed vertex creates a pentagonal prism cell, and diminishes two neighboring icosahedra into pentagonal antiprisms, and each octahedron into a square pyramid.

As the name suggests, it can be constructed by elongating a square pyramid ( " J " 1 ) by attaching a dual.

The summit somewhat resembles a ragged square pyramid and is visible from the Roaring Fork River valley north of Aspen along the canyon of Maroon Creek.

We can ( I hope ) all agree that a square pyramid ( of the Egyptian variety ) has 5 faces, 8 edges and 5 vertices.

The craft is able to transform and modify its mobility as a result between three configurations : a ball, an inverted square pyramid, and a gyroscope.

Also the cuboctahedron divides into 8 regular tetrahedra and 6 square pyramids ( half octahedron ), and it is the vertex figure for the alternated cubic honeycomb.
40.
Now consider the same cube where the square pyramid goes into the cube : this is concave, but the defects remain the same and so are all positive.
