Presentation

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

A minimal faithful permutation representation — 8 generators on 18 points:

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

Past the SmallGroups library coverage — no SmallGroups id. Construct it from a minimal faithful permutation representation:
