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

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

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