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