Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 256

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

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