Presentation

minimal degreeμ(G) = 32
transitive degreeμt(G) = 960

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

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