In geometry, the octahemioctacron is the dual of the octahemioctahedron, and is one of nine dual hemipolyhedra. It appears visually indistinct from the hexahemioctacron. Since the octahemioctahedron has four hexagonal faces passing through the model center, The octahemioctacron has four vertices at infinity. In Magnus Wenninger''s Dual Models, they are represented with intersecting infinite prisms passing through the model center, cut off at a certain point that is convenient for the maker.
