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