Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 128

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

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