Tetradiminished dodecateron

The tetradiminished dodecateron or teddot is a CRF polyteron, consisting 4 triangular duoprisms and 12 bidiminished rectified pentachora as facets. 6 rectified pentachora join at each triangular duoprismatic vertex. As the name suggests, it is can be created by removing an inscribed tetrahedron's vertices from a dodecateron.

It can be seen as a segmentoteron as bidiminished rectified pentachoron atop inverted bidiminished rectified pentachoron.
