Presentation

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

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

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