1820 conjugacy classes of subgroups; only the 59 normal subgroups are shown.

normal subgroups only

This group has 1820 conjugacy classes of subgroups — too many to draw. Only its 59 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 48

A minimal faithful permutation representation — 3 generators on 20 points:

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

Polycyclic presentation:

2^5,3,2^4|b^a=bd,c^a=ce,f^a=f^2,g^a=h,g^b=gi,g^d=gj,g^f=gh,h^a=g,h^b=hij,h^d=hi,h^f=g,i^a=j,i^f=j,j^a=i,j^f=ij
