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