Presentation

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

A minimal faithful permutation representation — 5 generators on 32 points:

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