Its nearest twin

Shares 3 of 5 numbers (17, 28, 31) with the draw of 4 December 2010 — its closest relative in 133 draws. Chance gave a match this close a 79% likelihood somewhere in that history.

From the draw just before (13 July 2011): 5 carried over. Chance says 54% of draws repeat at least one number.

Sum and shape

The numbers add up to 105 — the 66th percentile of all possible tickets, around a middle of 95. No two numbers side by side. 46% of draws have at least one such pair.

The longest wait in this draw

24 had not appeared for 17 draws. A number waits about 7 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.
