23250 conjugacy classes of subgroups; only the 82 normal subgroups are shown.

normal subgroups only

This group has 23250 conjugacy classes of subgroups — too many to draw. Only its 82 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 21
transitive degreeμt(G) = 80

A minimal faithful permutation representation — 3 generators on 21 points:

(2,3,4,5)(7,10,11,13)(8,12)(15,21)(18,19);(1,2,5,3,4)(7,8,10)(11,12,13)(15,16,18)(19,20,21);(6,10)(7,8)(9,13)(11,12)(14,18)(15,16)(17,21)(19,20)

Polycyclic presentation:

2^2,3,5,2^8|a^2=b,c^a=c^2,d^a=d^3,d^b=d^4,e^a=ef,e^c=f,f^c=ef,g^a=gh,g^c=h,g^f=gl,h^c=gh,h^e=hl,i^a=ij,i^c=j,i^f=ik,j^c=ij,j^e=jk
