Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 512

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

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