Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 560

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

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