Here's yet another.
The value of PI (sorry, symbol mapped out) in __nearly__ 22/7, but has
been calculated out to over 200 decimal places. The numbers are pseudo
random.
3.1415etc...
Lay out 200 digits. If you have parameters for your size of random
number, apply them (e.g. 7 digits). Take the first 2 digits (14), skip
14 digits, and begin your number there. Take the next 2 as the skip,
followed by the random. When you get to 200, wrap around so digit 201 --
> =1415etc
The early numbers (like the first) won't be random, but as long as you
don't restart in the same place, they'll be as random as you need. You'd
need a computer to determine whether they were random or pseudo random
and you don't have the use of that, do you ;-).
