Presentation

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

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

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