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

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

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