Except that you also want to know about quirks, which we can approximate as a binomial distribution where n is the size and p is 6/212 (it's not actually a true binomial); for a 50 point stone, of the surviving stones, roughly 23% will be unquirked, the rest will mostly have 1-3 quirks.
Or if you have trouble just with exponential notation, you can ignore this complexity and just use the formula in Magic. It's close enough.
