Presentation

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

A minimal faithful permutation representation — 6 generators on 28 points:

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