Presentation

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

A minimal faithful permutation representation — 7 generators on 18 points:

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