Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 128

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

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