Presentation

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

A minimal faithful permutation representation — 7 generators on 32 points:

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