Presentation

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

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

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