Here's a funny little chart that shows how the combos of 748 follow 844 throughout the history of the VA Pick 3. Time and again, when 844 falls straight, you count 36 days, play 748, and win. I noticed that 478/487 (combos of 748) also showed, so I included those in the chart with less bright highlighting.
