Galois action on the principal block and generation of Sylow 3-subgroups
Eden Ketchum, J. Miquel MartÃnez, Noelia Rizo +1
In this paper, we prove one direction of a conjecture of Navarro-Rizo-Schaeffer Fry-Vallejo positing an algorithm to determine from the character table whether a finite group has $…

Fixed point ratios, Sylow numbers and coverings of -elements in finite groups
Robert M. Guralnick, Attila Maróti, Juan MartÃnez Madrid +2
Fixed point ratios for primitive permutation groups have been extensively studied. Relying on a recent work of Burness and Guralnick, we obtain further results in the area. For a p…
