  1. Heptahedron
    • According to 3 sources
    A heptahedron (pl.: heptahedra) is a polyhedron having seven sides, or faces.
    A heptahedron is a polyhedron with seven faces. Because there are 34 heptahedral graphs, there are 34 topologically distinct convex heptahedra. There are three semiregular heptahedra: the pentagonal prism and pentagrammic prism (illustrated above), and a faceted version of the octahedron (Holden 1991).
    Heptahedron A polyhedron with 7 faces.

    List of uniform polyhedra - Wikipedia

    In geometry, a uniform polyhedron is a polyhedron which has regular polygons as faces and is vertex-transitive (transitive on its vertices, isogonal, i.e. there is an isometry mapping any vertex onto any other). It follows that all vertices are congruent, and the polyhedron has a high degree of reflectional and … See more

    Four numbering schemes for the uniform polyhedra are in common use, distinguished by letters:
