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