Presentation

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

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

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