Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 128

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

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