Its nearest twin

Shares 3 of 5 numbers (15, 25, 27) with the draw of 12 October 2010 — its closest relative in 244 draws. Chance gave a match this close a 97% likelihood somewhere in that history.

From the draw just before (19 July 2011): nothing carried over. Chance says 56% of draws repeat at least one number.

Sum and shape

The numbers add up to 128 — the 96th percentile of all possible tickets, around a middle of 90. Side-by-side numbers: 27–28. 48% of draws have at least one such pair.

The longest wait in this draw

33 had not appeared for 15 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 0.7× as often as an average ticket — less popular than most. At 30 million tickets sold, a winner on these numbers would keep about 2% of the jackpot.
