Presentation

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

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

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