Tetradiminished dodecateron

The tetradiminished dodecateron or teddot is a CRF polyteron, consisting of 4 triangular duoprisms and 12 bidiminished rectified pentachora as facets. It 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.
