Presentation

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

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

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