'''Antiprism''' — ''[[антипризма]].''  

The '''antiprism''' <math>\,A_{n}</math>, <math>n \geq 3</math>, is the [[plane graph|plane]] [[regular graph]] of [[degree of a graph|degree]] 4 (an Archimedean convex  polytope).

In particular, <math>\,A_{3}</math> is the octahedron.

The '''<math>\,k</math>-antiprism''' is the 4-regular plane graph consisting of two

<math>\,k</math>-gons and <math>\,2k</math> [[triangle|triangles]] such that every [[vertex]] is  incident  with

three triangles and one <math>\,k</math>-gon.
