Its nearest twin

Shares 3 of 5 numbers (11, 20, 31) with the draw of 19 June 2011 — its closest relative in 561 draws. Chance gave a match this close a 99% likelihood somewhere in that history.

From the draw just before (23 October 2011): 20 carried over. Chance says 48% of draws repeat at least one number.

Sum and shape

The numbers add up to 135 — the 82th percentile of all possible tickets, around a middle of 110. Side-by-side numbers: 36–37. 40% of draws have at least one such pair.

The longest wait in this draw

37 had not appeared for 28 draws. A number waits about 9 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 0.7× as often as an average ticket — less popular than most. At 30 million tickets sold, a winner on these numbers would keep about 4% of the jackpot.
