Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 512

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

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