Presentation

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

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

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