Its nearest twin

Shares 3 of 5 numbers (7, 20, 27) and 1 of 1 stars with the draw of 29 December 2012 — its closest relative in 359 draws. Chance gave a match this close a 96% likelihood somewhere in that history.

From the draw just before (14 September 2013): nothing carried over. Chance says 50% of draws repeat at least one number. Stars: none repeated (17% expected).

Sum and shape

The numbers add up to 74 — the 11th percentile of all possible tickets, around a middle of 105. No two numbers side by side. 42% of draws have at least one such pair.

The longest wait in this draw

20 had not appeared for 25 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 2.9× 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.
