Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 1920

A minimal faithful permutation representation — 4 generators on 28 points:

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