Under which conditions of temperate and pressure does oxygen gas behave least like an ideal gas

Under extremely high pressure and extremely low temperature. This is because part of the requirements of an ideal gas is that the atoms/molecules don't interact which brakes down at low temperatures and the atoms/molecules are point masses that have insignificant volumes compared to the volume the gas is in which breaks down at high pressures.

The four inner planets have slower orbits, slower spin, no rings, and they are made of rock and metal. The four outer planets have faster orbits and spins, a composition of gases and liquids, numerous moons, and rings. The outer planets are made of hydrogen and helium, so they are called gas giants. Cool stuff right?
