## Finite simple groups with few Galois orbits on conjugacy classes. (arXiv:1810.07421v1 [math.GR])

All finite simple groups with at most 4 Galois orbits on conjugacy classes are determined. From this we list all finite simple groups G for which the group of central units of the integral group ring ZG is isomorphic to <\pm 1> \times Z. 查看全文>>
