Presentation

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

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

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