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