Presentation

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

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

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