Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 512

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

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