Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 480

A minimal faithful permutation representation — 3 generators on 28 points:

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