Presentation

minimal degreeμ(G) = 27
transitive degreeμt(G) = 72

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

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