The binomial tree of order 0 consists of a single node. A binomial tree of order k is defined recursively by linking two binomial trees of order k-1: the root of one is the leftmost child of the root of the other.

Parameters
nint

Order of the binomial tree.

create_usingNetworkX graph constructor, optional (default=nx.Graph)

Graph type to create. If graph instance, then cleared before populated.

A binomial tree of \(2^n\) nodes and \(2^n - 1\) edges.
