Presentation

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

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

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