Presentation

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

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

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