Presentation

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

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

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