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