Presentation

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

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

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