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