Presentation

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

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

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