Description
Spherical \((3,2q)\) code for \(q \geq 2\) whose codewords are the vertices of a \(q\)-antiprism.Protection
The antiprism vertices consists of two \(q\)-gon vertices with the \(q\)-gons rotated by \(2\pi/q\) degrees. The relative height and radii of the \(q\)-gons can be modulated while still staying on the sphere. For the case when the two \(q\)-gons are such that the \(q=2,3\) cases reduce to the tetrahedron and octahedron, respectively, the antiprism is a spherical 3-design for \(q \geq 3\), and a \(2\)-design for \(q=2\) [1].Cousins
- Biorthogonal spherical code— The antiprism reduces to the octahedron for \(q=3\).
- Simplex spherical code— The antiprism reduces to the tetrahedron for \(q=2\).
