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