O2 - oxygen
O3 - ozone

Does O4 exist?

If it exists, I would imagine it to be extremely fragile (maybe a transient existence - even ozone is not that stable, but O4 would be very much less so).

Yes, it's very unstable. Amazingly, it's O8 to be more stable than O4:
http://en.wikipedia.org/wiki/Tetraoxygen

O8, also called "red oxygen", is formed compressing at room temperature common oxygen between 10 and 96 GPa (1 GPa ≈ 104 atm = 10,000 atm). At higher pressures it becomes metallic.

It's also interesting the colour variation of oxygen with pressure:
light blue --> pink --> orange --> dark red --> metallic. [:o]
