Presentation

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

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

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