Its nearest twin

Shares 3 of 5 numbers (1, 4, 13) with the draw of 1 February 2013 — its closest relative in 230 draws. Chance gave a match this close a 90% likelihood somewhere in that history.

From the draw just before (21 June 2013): nothing carried over. Chance says 52% of draws repeat at least one number.

Sum and shape

The numbers add up to 61 — the 5th percentile of all possible tickets, around a middle of 100. Side-by-side numbers: 13–14. 44% of draws have at least one such pair.

The longest wait in this draw

4 had not appeared for 16 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 1.4× 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.
