Its nearest twin

Shares 3 of 5 numbers (1, 20, 36) with the draw of 2 April 2011 — its closest relative in 520 draws. Chance gave a match this close a 99% likelihood somewhere in that history.

From the draw just before (12 September 2011): nothing carried over. Chance says 52% of draws repeat at least one number.

Sum and shape

The numbers add up to 112 — the 68th percentile of all possible tickets, around a middle of 100. Side-by-side numbers: 36–37. 44% of draws have at least one such pair.

The longest wait in this draw

1 had not appeared for 24 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 0.6× as often as an average ticket — less popular than most. At 30 million tickets sold, a winner on these numbers would keep about 3% of the jackpot.
