Presentation

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

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

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