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