For an orbit plane change (such as a LEO to a GEO), the Hohmann transfer orbit is the most efficient method.

What is an "orbit plane". Is it the same plane I was discussing in high school geometry? If we are talking about changing the height of a roughly circular orbit, where the old and new orbits are occupying roughly the same imaginary plane, cutting throught the earth--then do we have a case where hohmann transfer is the most efficient transfer strategy? (We are talking fuel-efficient, I presume.)
