Presentation

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

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

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