Presentation

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

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

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