Presentation

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

A minimal faithful permutation representation — 5 generators on 32 points:

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