Abstract
The author suggests that beta B, the critical exponent of the backbone of percolation clusters, is given by beta B=1/2( gamma +5 beta )-1, where gamma and beta are susceptibility and order parameter exponents of percolation respectively. The proposed relation agrees with the epsilon expansion of beta B given by Harris and Lubensky and provides accurate estimates of beta B at all d>1. This relation may suggest that the backbone exponents are not independent of other percolation exponents. The author also suggests a more general relation for the order parameter exponent of m-connected clusters.Keywords
