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