Presentation

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

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

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