Presentation

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

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

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