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