Rectified truncated tetrahedron

A rectified truncated tetrahedron is a geometric shape that results from the modification of a regular tetrahedron through two operations: truncation and rectification. 1. **Truncation**: This process involves cutting off the vertices of the tetrahedron. When you truncate a tetrahedron, you replace each of its four vertices with a new face (which, for a tetrahedron, will be a triangle). This operation creates additional edges and faces in the shape.
