construct Watkins snark graph
A snark is a nontrivial cubic graph with chromatic index 4.
The WatkinsSnark command creates a snark with 50 vertices.
G≔Graph 1: an undirected unweighted graph with 50 vertices and 75 edge(s)
H≔Graph 2: an undirected unweighted graph with 30 vertices and 45 edge(s)
The GraphTheory[SpecialGraphs][WatkinsSnark] command was introduced in Maple 2021.
For more information on Maple 2021 changes, see Updates in Maple 2021.
