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