Presentation

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

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

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