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