Presentation

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

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

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