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

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

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