Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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