Presentation

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

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

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