I have uploaded an excel file with my data and basic layout so that you can see what I am doing:

**ON49 by Seven Groups.xlxs**

**http://www.mediafire.com/?quggs7u1a1uwq1y**

You will notice that several of these groups are missing from each game -- the average is 3 groups missing, so we could be playing a

**6/28**game if we could time the play of 3 missing groups and choose the right 3! Four missing groups presents an even better opportunity and occurs about once a month, on average.

One thing that I have noticed is that these groups often cluster together -- 3 missing groups might include 2 consecutive groups (eg. Group1, Group2) or even 3 consecutives on occasion. Also, the missing groups often repeat at least one missing group from the previous game.

**If**I could count these bits of information they would be puzzle pieces that could help figure out the likely possibilities for the next game.

Can you help with counting the consecutives and repeat missing groups? I have tried some things, but can't seem to make it work.

Thanks,
