Presentation

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

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

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