Its nearest twin

Shares 3 of 5 numbers (9, 23, 31) with the draw of 26 December 2014 — its closest relative in 1,123 draws. Chance gave a match this close a 100% likelihood somewhere in that history.

From the draw just before (27 January 2015): nothing carried over. Chance says 55% of draws repeat at least one number.

Sum and shape

The numbers add up to 109 — the 76th percentile of all possible tickets, around a middle of 93. Side-by-side numbers: 31–32. 47% of draws have at least one such pair.

The longest wait in this draw

14 had not appeared for 7 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 0.8× as often as an average ticket — less popular than most. At 30 million tickets sold, a winner on these numbers would keep about 1% of the jackpot.
