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

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

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