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