Presentation

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

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

gap> G := Group((7,8)(9,10)(16,18), (1,2), (15,16,17,18), (7,8)(9,10), (4,6)(8,10)(11,12,13,14), (3,4)(5,6)(7,8)(9,10)(11,12)(13,14));
