In geometry, an octahedron is any polyhedron with eight faces. The most notable case is the regular octahedron, a Platonic solid made of eight equilateral triangles with four meeting at each vertex, though many irregular octahedra, both convex and non-convex, also exist.

Is Kind Of Object
Entity-backed identity for the object-kind enum value this mathematical object already carries, resolved to a mathematics concept by an explicit value-to-entity map (phase 3 bucket conversion, docs\design_entity_backed_browse_buckets_20260928.md). The object-kind fact itself stays on the object unchanged.
