normal subgroups only

This group has 7994168 conjugacy classes of subgroups — too many to draw. Only its 520296 normal subgroups are shown.

Dotted edges: containments with no intermediate normal subgroup — omitted non-normal subgroups may lie between.

Presentation

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

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

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

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

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