Presentation

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

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

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