Presentation

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

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

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