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:)

I will get back to you today or:) tomorrow wiht more specifics

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
