Presentation

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

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

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