Presentation

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

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

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