Its nearest twin

Shares 2 of 4 numbers (5, 20) and 0 of 1 stars with the draw of 29 November 2017 — its closest relative in 291 draws. Chance gave a match this close a 100% likelihood somewhere in that history.

From the draw just before (14 December 2017): nothing carried over. Chance says 40% of draws repeat at least one number. Stars: none repeated (4% expected).

Sum and shape

The numbers add up to 61 — the 28th percentile of all possible tickets, around a middle of 72. No two numbers side by side. 31% of draws have at least one such pair.

The longest wait in this draw

20 had not appeared for 15 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 1.2× 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.
