Torsion units in integral group ring of the Mathieu simple group M22

V. A. Bovdi, A. B. Konovalov and S. Linton



Abstract: We investigate the possible character values of torsion units of the normalized unit group of the integral group ring of the Mathieu sporadic group M22. We confirm the Kimmerle conjecture on prime graphs for this group and specify the partial augmentations for possible counterexamples to the stronger Zassenhaus conjecture.
