A k33 graph, also known as a complete bipartite graph, consists of two disjoint sets of vertices, where each vertex in one set is connected to every vertex in the other set. In this specific case, both sets contain three vertices each, making it a perfect example of how bipartite graphs can illustrate relationships between two different groups while maintaining a clear separation. Understanding k33 graphs helps in exploring properties of planar graphs and can be essential when applying Euler's formula.
congrats on reading the definition of k33 graph. now let's actually learn it.
