Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 128

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

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