Presentation

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

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

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