Minimum Viable Population for Humans?

Okay, this has been bugging me for a while, and I can't seem to find what I need online (though I did find the technical term!)

I have a small and completely isolated community. What I need to know is, what is the Minimum Viable Population for humans? That is, how small can this community be before they all die out due to not having enough genetic diversity? All I've been able to find via Google and Wikipedia has been explanations of what MVP is, studies of endangered species, and assorted completely incomprehensible (to me, at least!) equations.

My community needs to survive for about 500 years without any contact with the rest of the world, and I'd like it to be in fairly good shape at the end of that time, when it does start having outside contact. The people know enough about the dangers of inbreeding to keep track of genealogies and not interbreed too closely, but how large a starting population do they need?

Pointers to further resources and/or advice on search terms to use will also be gratefully received.

Edit: Thank you! I have my answer, and it's smaller than I'd thought. I shall stop worrying.
