Star Mesh

Computes intersections of lines from vertex i to vertex i + 2 to create a graph solved by Hierholzer
Size sides   random pc   Border

Simple Star

Connecting vertex i to vertex i + (side separation) - complete if sides and side_separation are relatively prime or
use Hierholzer to make a fully connected star
Size sides   side separation   random pc   Border   fully connected (if sides odd)

cardioid

Connecting vertex i to vertex 2*i mod sides - complete if sides is a primitive root of 2 see Sequence A167791
