Antitruncated tetrahedron

The antitruncated tetrahedron or inflected truncated tetrahedron is a semi-uniform polyhedron. It consists of 4 triangles and 4 tripods. It has 1 triangle and 2 tripods at a vertex, and an isosceles triangle vertex figure. It is the antitruncation of the tetrahedron and a faceting of a nonuniform rhombitetratetrahedron.

Variations
Adjusting the size of the triangles in an antitruncated tetrahedron but keeping the distance between them forms a teepee.
