Its nearest twin

Shares 3 of 6 numbers (8, 16, 37) with the draw of 23 April 2011 — its closest relative in 266 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 54% of draws repeat at least one number.

Sum and shape

The numbers add up to 180 — the 72th percentile of all possible tickets, around a middle of 159. No two numbers side by side. 47% of draws have at least one such pair.

The longest wait in this draw

16 had not appeared for 17 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 0.5× as often as an average ticket — less popular than most. At 30 million tickets sold, a winner on these numbers would keep about 70% of the jackpot.
