Presentation

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

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

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