Presentation

minimal degreeμ(G) = 18
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 6 generators on 18 points:

(1,2);(3,4,5,6)(8,10)(11,12,15,13)(14,16,18,17);(3,4)(5,6)(7,8,9,10)(11,12,15,13)(14,17,18,16);(3,4)(5,6)(12,13)(16,17);(11,13,15,12)(14,16,18,17);(11,14,15,18)(12,16,13,17)
