Not a true homework question, but I'm trying to find all subgroups of S4.
Including the identity and the group itself, I've found 30. Is that correct?
I've got groups such as:
trivial
s4
alternating group
{identity, (12)}, {identity, (13)} etc - 6 of these
{identity, (123), (132)}, {identity, (124), (142)} etc - 4 of these
{identity, (12)(34)}, {identity, (13)(24)} etc - 3 of these
{identity, (1243), (14)(23), (1342)} etc - 3 of these
{identity, (13), (24), (12)(34), (13)(24), (14)(23), (1234), (1432)} - 3 of these
{identity, (12), (34), (12)(34)} etc - 3 of these
{identity, (123), (132), (12), (23), (13)}, {identity, (124), (142), (12), (24), (14)} etc - 4 of these.
{identity, (12)(34), (13)(24), (14)(23)}
Am I missing any?
