Presentation

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

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

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