Presentation

minimal degreeμ(G) = 32
transitive degreeμt(G) = 256

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

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