Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain Archimedean solids, relay their definition, the thirteen solids, symmetry and duals from geometry sources, describe the named examples, and distinguish Archimedean solids from Platonic solids, Johnson solids, Catalan solids and prisms and antiprisms.

One of thirteen highly symmetric convex polyhedra whose faces are two or more kinds of regular polygon meeting identically at every vertex, more symmetric than the Johnson solids but less than the five Platonic solids, with examples the registry aliases name such as the truncated icosahedron, the shape of a classic football, the icosidodecahedron, the truncated dodecahedron and octahedron, and the chiral snub cube and snub dodecahedron; Archimedean solids are named after Archimedes and are studied in geometry, with duals called the Catalan solids. Counting conventions vary slightly for chiral forms.

What it is for: A class of highly symmetric semiregular polyhedra.

It can be explain the definition; relay the thirteen solids and symmetry; describe named examples; distinguish related solids.

Distinguishing features

Two or more regular polygon faces

Identical vertices

Thirteen solids

Catalan duals

What it looks like

Convex solids with faces of two or more regular polygon types, such as a football shape.

Physical character

number: 13 count - plus chiral pairs

vertices: all identical note - vertex-transitive

registry parent: convex polyhedron note

How it is recognised

Semiregular convex polyhedron with identical vertices

Truncated icosahedron, icosidodecahedron, truncated dodecahedron, snub cube, snub dodecahedron, truncated octahedron

Platonic solids have one face type; Johnson solids are less symmetric; Catalan solids are the duals; prisms and antiprisms are separate infinite families
