Presentation

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

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

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