%0 Journal Article %T On the number of classes of conjugate Hall subgroups in finite simple groups %A D. O. Revin %A E. P. Vdovin %J Mathematics %D 2009 %I arXiv %R 10.1016/j.jalgebra.2010.09.014 %X In this paper we find the number of conjugate $\pi$-Hall subgroups in all finite almost simple groups. We also complete the classification of $\pi$-Hall subgroups in finite simple groups and correct some mistakes from our previous paper. %U http://arxiv.org/abs/0912.1922v2
