An attempt to build a minimal one of these objects is a problem named for Jakob Steiner.
The number of these structures of a given size is given by the formula n raised to the n-2 power, which is named for Arthur Cayley. An attempt to build a minimal one of these objects is a problem named for Jakob Steiner. Binary heaps use a binary type of this structure, in which nodes beyond the first one are classified as left or right when they are added. Each pair of vertices in these structures are connected by exactly one simple path. Name these types of undirected bipartite graphs.
