Some Reality Properties of Finite Simple Orthogonal Groups
Jiwon Kim, Stephen Trefethen, C. Ryan Vinroot
We prove several reality properties for finite simple orthogonal groups. For any prime power and , we show that all real conjugacy classes are strongly real in the sim…

A computational approach to the Frobenius-Schur indicators of finite exceptional groups
Stephen Trefethen, C. Ryan Vinroot
We prove that the finite exceptional groups , , and have no irreducible complex characters with Frobenius-Schur indicator , and we list e…
