Its nearest twin

Shares 3 of 5 numbers (7, 14, 22) with the draw of 8 December 2011 — its closest relative in 617 draws. Chance gave a match this close a 100% likelihood somewhere in that history.

From the draw just before (20 December 2011): 22 carried over. Chance says 63% of draws repeat at least one number.

Sum and shape

The numbers add up to 79 — the 52th percentile of all possible tickets, around a middle of 78. No two numbers side by side. 54% of draws have at least one such pair.

The longest wait in this draw

26 had not appeared for 16 draws. A number waits about 6 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 0% of the jackpot.
