Presentation

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

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

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