Butterfly graph

Summary

In the mathematical field of graph theory, the butterfly graph (also called the bowtie graph and the hourglass graph) is a planar, undirected graph with 5 vertices and 6 edges. It can be constructed by joining 2 copies of the cycle graph C3C_{3} with a common vertex and is therefore isomorphic to the friendship graph F2F_{2}.
