Presentation

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

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

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