Its nearest twin

Shares 3 of 5 numbers (20, 36, 38) with the draw of 18 February 2012 — its closest relative in 734 draws. Chance gave a match this close a 100% likelihood somewhere in that history.

From the draw just before (16 April 2012): 22 carried over. Chance says 52% of draws repeat at least one number.

Sum and shape

The numbers add up to 148 — the 98th percentile of all possible tickets, around a middle of 100. No two numbers side by side. 44% of draws have at least one such pair.

The longest wait in this draw

20 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 0.4× as often as an average ticket — less popular than most. At 30 million tickets sold, a winner on these numbers would keep about 5% of the jackpot.
