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

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

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