Well you're very good at quoting the SABRE Wiki (of which I wrote a not inconsiderable amount!).

Well, I do change the odd word here and there...

That's really quite surprising - not about that particular number, but that the pattern of numbers with that property is so irregular.

Don't give away your route secrets!! You have no concept of privacy now I can break that elusive 6 hour barrier.

Pipped at the post! I looked to see what it had to say about Twerton, the district of Bath where I currently live: "Nigel de Gournai and Geoffrey Malregard from Bishop of Coutances. 4 mills. 4 cobs, 17 cattle, 35 pigs, 400 sheep". I doubt whether William the Conqueror would recognize it now

Take this new number, and below it, write the number backwards. Then add the two together.

Your answer should be 1089.

This isn't quite right. It should begin "Take any three-digit number that isn't a palindrome. Write it backwards. Take away the smaller from the larger..." [etc.]

So for instance starting with 762, you get 762 - 267 = 495; 495 + 594 = 1089.

It's a neat trick though!

Ah yes - I wrote it in a hurry. Thanks for correction; I've updated the main entry now.

I can certainly bear it in mind - just in case I get sacked soon...

[I don't think a single Tube-related fact has ever been posted on this thread! Now there's a challenge...]

St Anselm of Canterbury, who developed the so-called "ontological argument" for the existence of God, died in AD 1109.

Not true!

- From myself: British Rail Class 483 is another name for the 1938 Tube Stock trains, which last ran the Tube on the Northern line in 1988. They now run on the Isle of Wight.
- From greatkingrat: Pantone 485 is the colour of the Central line on the underground map.
- From Brock: Thanks. I'm afraid I don't have anything interesting to say about the number 539, except that it's the total number of stations you'd visit in two Tube Challenges. If you left one out the first time

I stand corrected! Although I don't really think the last one qualifies

I like it. I bet Andi could run it in a few minutes.

I can write it with 23 letters: "eleven hundred and fifteen".

Even if you disallow "eleven hundred", I'd dispute the wording of your statement, since "one thousand one hundred and thirteen" is 32 letters long and hence requires 31 letters. Did you mean the smallest integer requiring exactly 31 letters?

We have a bit of a way to catch up!

Yes, but they aren't uploading interesting facts.
