minimal degreeμ(G) = 28
transitive degreeμt(G) = 512

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

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