Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 256

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

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