Let a random (0,1)-matrix have entries which are 1 (with probability ) or 0 (with probability ) and numbers are assigned to the edges of a grid. A -cluster is an isolated group of adjacent (i.e., horizontally or vertically connected) 1s. Let be the total number of "bond" clusters, then
exists. The analytic value is known for ,
