The Triaugmented Hexagonal Prism

The triaugmented hexagonal prism (J57) is the 57th Johnson solid. It has 9 vertices, 21 edges, and 14 triangular faces. It can be constructed augmenting a hexagonal prism with 3 square pyramids.

If an augment is removed, the metabiaugmented hexagonal prism (J56) is obtained. If two augments are removed, the augmented hexagonal prism (J54) is produced.
