Abstract
In this paper we improve the previously achieved upper bound on the corank of an equivariantly stable singularity for a group of prime order. We also prove that the maximal corank of a simple -invariant germ tends to infinity as increases and is asymptotically logarithmic, so the previously obtained bound is valid up to order of magnitude.
