Presentation

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

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

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