The equilateral triaugmented triangular prism is the Johnson solid 
constructed by erecting a regular tetrahedron on each square face of an equilateral triangular prism.It is a convex deltahedra composed of 14 equilateral triangles.
It is implemented in the Wolfram Language as PolyhedronData["TriaugmentedTriangularPrism"].
The skeleton of the triaugmented triangular prism is the Fritsch graph.
The polyhedron vertices are

, where the 
and 
coordinates of the last are found by solving
