I suppose this has no direct connection with 'the Prisoner,' and yet the series is all about numbers. Yesterday morning I was listening to the morning programme on BBC Radio 4. And there was this guy Alex Bellos who had been carrying out research into the world's favourite number, well it's a bit of fun really. What might you think that number is? What's your favourite number, it wouldn't be 6 by any chance? As it works out the world's favourite number is 7. And as you know 7 only appears in 'the Prisoner' by surreptitious means, like the Lotus seven, the seven times No.2 slaps No.6's face in 'Free For All.' The seven ages of man, the digit 7 in 73, etc, etc. Also according to recent research which I heard on the programme on BBC Radio 4. That if we consider only the basic number grouping of 1 to 10, 1 2 3 4 and 5 can be divided. 6 8 and 10 can be halved. 9 can be divided by three, and 7 is left on it's own. 7 is said to be unique, because it can neither be divided or multiplied., which is lucky for 7, being a lucky number!
