Presentation

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

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

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