Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 256

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

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