Its nearest twin

Shares 2 of 5 numbers (39, 42) with the draw of 22 November 2018 — its closest relative in 38 draws. Chance gave a match this close a 98% likelihood somewhere in that history.

From the draw just before (11 December 2018): nothing carried over. Chance says 48% of draws repeat at least one number.

Sum and shape

The numbers add up to 138 — the 85th percentile of all possible tickets, around a middle of 110. No two numbers side by side. 40% of draws have at least one such pair.

The longest wait in this draw

42 had not appeared for 20 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 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 4% of the jackpot.
