This has maybe gone on long enough...let me know if you think so and I'll reveal all.
If you'd like an alternative question....what sequence starts with 70 and continues with 836? If not, please ignore and perhaps Yorkie can continue having got a third of the answer!

Numbers the sum of whose divisors is more than one greater than themselves. Because abundant for numbers the sum is just greater than the original, while for pseudoperfect numbers it’s exactly one more.
I googled it
Roy Castle, Matthew Fort, General Alcazar...surnames all to do with built, usually military, defences.

Close enough I think...they're known to mathematicians as weird numbers because in addition to the divisors adding up to a greater number than themselves, the divisors can't be made to add up to the number itself (1 not being considered a divisor).
Thanks Theo, although I feel a bit guilty since I used Google.
In 1900 it became the first Olympic event in which women were allowed to participate. However, lack of interest (just one spectator bought a ticket and only the French entered) meant it was never re-introduced. Also, Leon Trotsky was a fan. What is it?

When a group of softballers from here travel off-island to play matches where they aren't playing as the island side, their team name is Bean Machine. What is a Bean Machine and where is there a working replica?

It just shows that life can be reduced to probability or a mathermatical theorem
The bean machine, also known as the quincunx or Galton box, is a device invented by Sir Francis Galton[1] to demonstrate the central limit theorem, in particular that the normal distribution is approximate to the binomial distribution. Among its applications, it afforded insight into regression to the mean or "regression to mediocrity".
The machine consists of a vertical board with interleaved rows of pins. Balls are dropped from the top, and bounce left and right as they hit the pins. Eventually, they are collected into one-ball-wide bins at the bottom. The height of ball columns in the bins approximates a bell curve.
Overlaying Pascal's triangle onto the pins shows the number of different paths that can be taken to get to each bin.
A large-scale working model of this device can be seen at the Museum of Science, Boston in the Mathematica exhibit (currently closed
)Interesting it demonstrates standard deviations etc
