Presentation

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

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

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