  Spiral (gyrotropic) percolation which is related to the behavior of an
electron system in strong magnetic fields is studied. It is shown that the
scaling behavior area near the percolation threshold is anomalously narrow. The
percolation threshold is higher than in a system with usual isotropic
percolation (i.e., it is at higher concentrations of undamaged structure
elements). Our old value of the critical exponent of the correlation length is
corrected.
