Presentation

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

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

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