The **biaugmented triangular prism** is one of the 92 Johnson solids (J_{50}). It consists of 2+2+2+4 triangles and 1 square. It can be constructed by attaching square pyramids to two of the square faces of the triangular prism.

## Vertex coordinates[edit | edit source]

A biaugmented triangular prism of edge length 1 has the following vertices:

## In vertex figures[edit | edit source]

Variants of the biaugmented triangular prism (in its symmetry axis, with non-base connected edge lengths of √2) by changing the edge opposite to the square appear as the vertex figure of the nonuniform antiditetragoltriate, and has no corealmic realization.
