I realize this might be not be a challenge for some of you.

I need to make a list of all possible permutations given 9 options and
that you can choose any number of options at once.
I've figured out using nCr statistics that this is 511 choices, but now
I need to represent them in 2^9 binary code: 000000001, 000000010 etc
Anyone got a quick way? I thought about writing a python code or
something but then I got confused just thinking about the algorthim.
Now the best would be if you had an idea that I could implement with my
limited toolset: R, OpenOffice, Python, and I guess I could add a
package to Cygwin if necessary.
Thanks,
Alex
