Presentation

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

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

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