Presentation

minimal degreeμ(G) = 18
transitive degreeμt(G) = 128

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

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