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