Pentacontahexadiminished birectified hecatonicosoctaexon

The pentacontahexadiminished birectified hecatonicosoctaexon or lidbarz is a convex scaliform polyexon. It consists of 14 hexeractidiminished rectified hexacontatetrapeta, 56 triangular-hexadecachoric duoprisms, and 128 heptadiminished birectified heptapeta. 3 hexeractidiminished rectified hexacontatetrapeta, 6 triangular-hexadecachoric duoprisms, and 16 birectified heptapeta meet at each vertex.

One can create this polyexon by removing 56 vertices (corresponding to an inscribed hecatonicosihexapentacosiheptacontahexaexon) from a birectified hecatonicosoctaexon.
