Presentation

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

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

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