Presentation

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

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

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