Note: {m,n} is the Shläfli symbol, signifying a hyperbolic lattice in which n regular m-gons meet at every vertex
Cayley tree (Bethe latttice) with coordination number z: pc= 1 / (z - 1)
Cayley tree with a distribution of z with mean, mean-square pc= (site or bond threshold)

Famous quotes containing the word tree:
“The wind had seized the tree and ha, and ha,
It held the shivering, the shaken limbs,
Then bathed its body in the leaping lake.”
—Wallace Stevens (18791955)
