Cayley tree with grandparents 8 0.158656326

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 (1879–1955)
