Presentation

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

A minimal faithful permutation representation — 7 generators on 28 points:

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