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