Presentation

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

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

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