A property of a lattice. Related to the rate at which the number of

self-avoiding walks on the lattice grows (*c*_{n}) with the

number of steps. Since it is known that the limit as *n* goes to

infinity of 1/*n*(log *c*_{n}) exists, it

is possible to define the value of the limit as being the growth

constant of the lattice, usually denoted by the Greek letter mu.

The connective constant is the logarithm of

this value, often denoted by the Greek letter kappa.
