Presentation

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

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

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