It would take me a little time to come up with the structure.

It even has a train station which has a sign that spells it out in full; on most maps it's shown as Llanfair. Can you pronounce it?

The 670e6 number is the speed in miles per > hour. I usually remember the longer number, and calculate the smaller from it! There's a pattern in the digits: [6] 0 1 2 3 7 6 5 4 ----------- 670615243 :) That and the fact that my 'phone number starts "670" (and that my 'phone number's prime, but that's a different matter) :) However I will admit that both are approximated to fit in with the rule-of-thumb. > >16777216,,, 1024576,,, 262144, 131076, 65536, [49152,] 32768, 16384, 8192, > >4096, 2048, 1024, 512... > > I recognize the numbers; I don't see the significance of the > series. Powers of two from 2^24 to 2^9. ",,," means I've forgotten :) [] means "in the middle" ...256, 128, 64, 32, 16, 8, 4, 2, 1, 0.5, 0.25, 0.125, 0.0625, 0.03125, 0.015625.
