Title  Sagbi Basis Of Permutation Groups And Convex Cones  Author(s)  Nicolas M. Thiery, Stephan Thomasse  Type  Technical Report, Misc  Abstract  Let G be a permutation group acting on {1, ... ,n}, and < be any admissible term order on the polynomial ring K[x1, ... ,xn]. We prove that the invariant ring K[x1, ... ,xn]^G of G has a finite SAGBI basis if and only if G is generated by reflections.
