Presentation

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

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

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