Presentation

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

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

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