Lower bound on the connective constant for square lattice self-avoiding walks
Andrew R. Conway, Anthony John Guttmann · Journal of Physics A Mathematical and General · 1993
By enumerating irreducible bridges exactly up to 40 steps, and by obtaining a lower bound to the number of bridges with less than 125 steps, a lower bound for the connective constant for square lattice self-avoiding walks of 2.62 is obtained.
