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