Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 4 generators on 32 points:

(1,2)(3,6)(4,5)(7,8)(17,18,20,24,21,23,27,30)(19,22,26,29,25,28,31,32);(2,5)(6,8)(9,10,11,14,12,13,15,16)(19,25)(22,28)(26,31)(29,32);(17,19,20,26,21,25,27,31)(18,22,24,29,23,28,30,32);(1,3,4,7)(2,6,5,8)(10,13)(14,16)(18,23)(22,28)(24,30)(29,32)
