Hi Jack,

If we take out the numbers with duplicate digits from numbers 00 to 99 we are left with 90 numbers.
Now if we want to produce ALL the 4 number combinations from these 90 numbers we end up with a total of C(90,4) = 2,555,190 combinations.
Is this what you are after?

Regards,
PAB

12:45, restate my assumptions.
Mathematics is the language of nature.
Everything around us can be represented and understood through numbers.
If you graph the numbers of any system, patterns emerge. Therefore, there are patterns everywhere in nature.

Hi Jack,

I have noticed that you have NOT started a new thread as RAMROCK suggested.
Can I assume that you have got an answer to your request?
If you have, perhaps you could post your method so others on this forum following this thread can see what the solution was?
If you haven't, then if you start a new thread as suggested then we can probably supply a solution for you.
