Presentation

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

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

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