Presentation

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

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

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