Presentation

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

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

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