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