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