Presentation

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

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

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