Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 512

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

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