A Cayley tree is a tree in which each non-leaf graph vertex has a constant number of branches is called an
-Cayley tree. 2-Cayley trees are path graphs. The unique
-Cayley tree on
nodes is the star graph. The illustration above shows the first few 3-Cayley trees (also called trivalent trees, binary trees, or boron trees). The numbers of binary trees on
, 2, ... nodes (i.e.,
-node trees having vertex degree either 1 or 3; also called 3-Cayley trees, 3-valent trees, or boron trees) are 1, 1, 0, 1, 0, 1, 0, 1, 0, 2, 0, 2, 0 ,4, 0, 6, 0, 11, ... (OEIS A052120).
The illustrations above show the first few 4-Cayley and 5-Cayley trees.
The percolation threshold for a Cayley tree having branches is
