Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 128

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

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