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