Presentation

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

A minimal faithful permutation representation — 3 generators on 32 points:

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