## Integral group ring of the Mathieu simple group $$M_{24}$$.(English)Zbl 1247.16032

Continuing a series of papers by the authors, for instance, a recent one is [Stud. Sci. Math. Hung. 47, No. 1, 1-11 (2010; Zbl 1221.16026)], for the integral group ring of the Mathieu simple group $$M_{24}$$ the Kimmerle conjecture on prime graphs is verified by a method due to I. S. Luthar and I. B. S. Passi.
