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

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

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