Presentation

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

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

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