Its nearest twin

Shares 3 of 5 numbers (6, 17, 18) with the draw of 9 September 2010 — its closest relative in 139 draws. Chance gave a match this close a 78% likelihood somewhere in that history.

From the draw just before (15 September 2010): nothing carried over. Chance says 53% of draws repeat at least one number.

Sum and shape

The numbers add up to 88 — the 34th percentile of all possible tickets, around a middle of 98. Side-by-side numbers: 17–18, 23–24. 45% of draws have at least one such pair.

The longest wait in this draw

17 had not appeared for 6 draws. A number waits about 8 on average, and a wait this long was not a signal — the machine has no memory of it.

How many people held it

A line like this is played about 1.6× as often as an average ticket — more popular than most. At 30 million tickets sold, a winner on these numbers would keep about 1% of the jackpot.
