Its nearest twin

Shares 3 of 6 numbers (8, 19, 20) with the draw of 27 July 2011 — its closest relative in 241 draws. Chance gave a match this close a 100% likelihood somewhere in that history.

From the draw just before (17 October 2011): nothing carried over. Chance says 71% of draws repeat at least one number.

Sum and shape

The longest wait in this draw

19 had not appeared for 10 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 1.8× as often as an average ticket — more popular than most. At 30 million tickets sold, a winner on these numbers would keep about 3% of the jackpot.
