600 conjugacy classes of subgroups; only the 90 normal subgroups are shown.

normal subgroups only

This group has 600 conjugacy classes of subgroups — too many to draw. Only its 90 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 39
transitive degreeμt(G) = 608

A minimal faithful permutation representation — 3 generators on 39 points:

(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19)(21,22)(24,25,28,31)(26,32,34,39)(27,30,35,38)(29,36,37,33);(20,21)(22,23)(27,35)(30,38);(20,22,23,21)(24,26)(25,29)(27,33)(28,34)(30,32)(31,37)(35,36)(38,39)
