Presentation

minimal degreeμ(G) = 32
transitive degreeμt(G) = 64

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

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