✦ Synopsis


By using a fast, Nested Dissection algorithm we compare the results of finite-size scaling at p c and of ''p'' scaling (L = const) on large cubic random resistor networks [up to 500 × 500 × 500]. The ''p'' scaling for conductivity of both site and bond networks leads to an exponent t = 2.00(1). The finite-size scaling leads to the ratio of this conductivity exponent to the coherence length exponent ν: t/ν = 2.283(3). Combining these results we estimate ν = 0.876(6), in excellent agreement with a value proposed by Ballesteros et al. The first-order correctional exponent ω is found to be ω = 1.0(2).
