Presentation

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

A minimal faithful permutation representation — 3 generators on 32 points:

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