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