Presentation

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

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

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