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