Presentation

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

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

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