Its nearest twin

Shares 3 of 5 numbers (17, 22, 30) with the draw of 22 October 2010 — its closest relative in 291 draws. Chance gave a match this close a 99% likelihood somewhere in that history.

From the draw just before (23 January 2011): nothing carried over. Chance says 57% of draws repeat at least one number.

Sum and shape

The numbers add up to 90 — the 54th percentile of all possible tickets, around a middle of 88. No two numbers side by side. 49% of draws have at least one such pair.

The longest wait in this draw

2 had not appeared for 6 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 1.5× 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.
