Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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