Presentation

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

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

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