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

A minimal faithful permutation representation — 5 generators on 28 points:

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