1516 conjugacy classes of subgroups; only the 43 normal subgroups are shown.

normal subgroups only

This group has 1516 conjugacy classes of subgroups — too many to draw. Only its 43 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 17
transitive degreeμt(G) = 60

A minimal faithful permutation representation — 2 generators on 17 points:

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

Polycyclic presentation:

2^4,3,5,2^4|a^2=d,b^2=c,b^a=bd,e^b=e^2,f^b=f^3,f^c=f^4,g^a=gi,g^e=h,h^a=hj,h^b=gh,h^e=gh,i^e=j,j^b=ij,j^e=ij
