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