Octadiminished demihepteract

The octadiminished demihepteract, or odhesa, is a convex scaliform polyexon. It has 8 heptapeta, 8 rectified heptapeta, and 14 tetradiminished demihexeracts as facets; 1 heptapeton, 3 rectified heptapeta, and 7 tetradiminished demihexeracts meet at each vertex.

As its name suggests, the octadiminished demihepteract is constructed by removing 8 vertices (corresponding to a scaled octaexon) from a demihepteract.

Perhaps surprisingly, the octadiminished demihepteract is the diacositetracontadiminished diacositetraconta-myriaheptachiliadiacosioctaconta-zetton's vertex figure.
