The site is down........it's been aggravating me because I wanted to see it so I started searching and here is a link to a forum page where somebody found a cached copy of the tables for singles, twins and triplets from the betabase site. Once your on the page just go down a little bit and you'll see the tables.......hope this helps!!! (not sure you may have to copy and paste this)
