Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 512

A minimal faithful permutation representation — 7 generators on 28 points:

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