Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 64

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

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