Presentation

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

A minimal faithful permutation representation — 5 generators on 32 points:

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