In the main draw of the National Lottery six different numbers between 1 and 49 inclusive are selected at random live on television. My sister and I both buy a ticket every week. Whenever one of us is not able to watch the draw the other texts the numbers the instant the sixth one is revealed. e.g. 15, 46, 20, 31, 5, 22 One week however, my sister forgot to leave gaps between the numbers and I received the following: 3437427337 Luckily, upon closer scrutiny, I could see that there was only one arrangement possible.
