Presentation

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

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

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