Presentation

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

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

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