Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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