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