Hi bobbym,
Ok... how long would it take to upload a 12mb file ?
Are you not on ADSL ? Could you write the code
and I could execute the program on my machine ?
Cheers
Chris

Hi bobbym,
I understand the technical difficulties
but what about file transfer hositng sites ?
I am a subscriber of
transferbigfiles.com The only
problem is that files must be no more
than 100mb in size and maybe for the 7 numbers
combination file we can break the file up into 7
separate files ?
For 5 = 12 MB
For 6 = 97 MB
For 7 = 635 MB
Cheers
Chris

Hi bobbym,
I am back again and still working out the refinement of what I need.
Whilst I am doing so you I would still be interested in creating these
files just the same.
What format would they be in ?
Cheers
Chris

Hi bobbym,
Ok ... What I will do is give you more details and
the parameters around what I need to achieve.
I will not be able to do this until sometime
tomorrow, but really look forward in hoping
something can be done
Cheers
Chris

Hi b:)obbym,
Then if so how would you go about it ?
Cheers

Hi bobbym,
Sorry you are right ... true...
I meant to refer to the different combinations that can be obtained
With those combination results does that still make the task and output
just as daunting ?:)

Hi Bobby,
Just out of curiosity I did a permutation calulation and found that there are
45,379,620 permutations of 7 numbers from 1 to 45 and
8,145,060 permutations of 6 numbers from 1 to 45 and
1,221,759 permutations of 5 numbers from 1 to 45
assuming 1. Order of numbers is not important
2. Cannot repeat a number
Cheers
Chris:)

Hi all,
I know there are limitations and this may be a far out request (I am aware of the millions of permutations), but I would like to know if someone knows how to produce all possible permutations of 5 numbers using numbers from 1 to 45 as well as applying this to 6 and 7 numbers and dumping in an external database with some sort of query tools to filter certain permutations for further analysis.
Once again I know this is a "big ask" and the files maybe many and very LARGE but
would love to hear back from someone..:)
I look forward in hearing back from you soon.
Regards
Chris
