Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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