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