Editing Antiprism (section)

=== Uniform antiprism ===
A '''[[Prismatic uniform polyhedron|uniform]] {{mvar|n}}-antiprism''' has two [[Congruence (geometry)|congruent]] [[Regular polygon|''regular'']] {{mvar|n}}-gons as base faces, and {{math|2''n''}} [[Equilateral triangle|''equilateral'']] triangles as side faces. As do uniform prisms, the uniform antiprisms form an infinite class of vertex-transitive polyhedra. For {{math|''n'' {{=}} 2}}, one has the digonal antiprism (degenerate antiprism), which is visually identical to the regular [[tetrahedron]]; for {{math|''n'' {{=}} 3}}, the regular [[octahedron]] is a ''triangular antiprism'' (non-degenerate antiprism).<ref name=oh/>
