Abstract: Abstract Let G be a transitive permutation group on a finite set Ω. If G is multiplicity-free, then End G ( C [ Ω ] ) is commutative, and Krein parameters q i , j… read more here.

Abstract: We study the orbits under the natural action of a permutation group $G \subseteq S_n$ on the powerset $\mathscr{P}(\{1, \dots , n\})$. The permutation groups having exactly $n+1$ orbits on the powerset can be characterized… read more here.
