Presentation

minimal degreeμ(G) = 27
transitive degreeμt(G) = 224

A minimal faithful permutation representation — 4 generators on 27 points:

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