Hi, I am unsure how to put this and my math skills aren't that strong. But here's what I need.

I want to generate a list of all the 16bit integers (0-65535). But everytime I do so I want to seed the algorithm randomly that each time the list starts with a different integer and all the subsequent integers will be generated once but also in random order.

small example (1-5): ...

1, 5, 3, 2, 4

4, 3, 1, 5, 2

2, 1, 4, 5, 3 ...

Any help?

Anyone have experience with Quick Sequence Diagram Editor? The combination of instant display + text source code + Java implementation is very attractive to me, but I can't quite figure out how to make the syntax do what I want, and the documentation's not very clear.
