Presentation

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

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

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