Presentation

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

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

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