minimal degreeμ(G) = 28
transitive degreeμt(G) = 128

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

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