Presentation

minimal degreeμ(G) = 32
transitive degreeμt(G) = 1920

A minimal faithful permutation representation — 3 generators on 32 points:

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