Presentation

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

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

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