Paccekabuddha = A silent buddha. One who attains full enlightenment, but does not teach others. He attains enlightenment during a time when there is no Dhamma dispensation.
Arahant = Fully enlightened person, who might teach others, but not as the one who rediscovered the teachings, just as one who learned it from a current dispensation.
All are fully enlightened, hard to attain. But simply using statistics, the Arahant would be the "easiest" to attain of the three above. Samma-sam-buddhas and Pacceka-buddhas are very rare, but there were several thousand monks and nuns (and a few lay people) who attained full enlightenment during the Buddha's lifetime, as recorded in the Pali Canon.
I would of agreed fully with each of these a couple of months ago, but there has been a fairly recent paper on the Paccekabuddha that shows they do teach.
I heard a while ago (3+years) that there is a sambuddha also (yes minus the samma) that teaches but it doesn't last a long time (in a Ajahn Vajiro talk on the perfections). they taught only what was needed through supernormal powers so didn't need to give detailed instructions on a techneque, they only needed to say do this & that and the job was done teaching wise.
I will find the paper (short pointing out) and link it soon.
OK Really glad I didn't say this was by Analayo, as I suspected
It is by Venerable Anandajotihttp://www.ancient-buddhist-texts.net/T ... akatha.htm
short but very sweet!
