Non-isomorphic groups with isomorphic spectral tables and Burnside matrices
The authors present examples of pairs of groups \(G\) and \(H\) such that 1) \(G\) and \(H\) form a Brauer pair, 2) \(G\) and \(H\) have the same Burnside matrix (table of marks), 3) \(G\) and \(H\) have the same 2-characters in the sense of Frobenius, and 4) \(G\) and \(H\) are not isomorphic.
