Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 256

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

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