Presentation

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

A minimal faithful permutation representation — 3 generators on 27 points:

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