Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 64

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

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