minimal degreeμ(G) = 28
transitive degreeμt(G) = 256

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

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