Its nearest twin

Shares 3 of 5 numbers (17, 30, 39) with the draw of 10 July 2011 — its closest relative in 621 draws. Chance gave a match this close a 100% likelihood somewhere in that history.

From the draw just before (21 December 2011): 39 carried over. Chance says 52% of draws repeat at least one number.

Sum and shape

The numbers add up to 125 — the 84th percentile of all possible tickets, around a middle of 100. Side-by-side numbers: 16–17. 44% of draws have at least one such pair.

The longest wait in this draw

30 had not appeared for 7 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 0.8× as often as an average ticket — less popular than most. At 30 million tickets sold, a winner on these numbers would keep about 2% of the jackpot.
