Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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