Hi Agnishom;

That and many, many more things.

Hmmm...
I asked my father and he said that it is used to solve problems like differential equations.

Hi Agnishom;

Mathematica is a program that does mathematics. You will be exposed to it when you get to college and certainly when you find a job.

I understand that but what is Mathematica?

Hi Agnishom;

I would use mathematica to print the files in theory. In reality, I would never do such a thing. Why? Because there is almost always a better way than looking at all the permutations.

I was talking about the code for the program which generated those databases.
Would you show us that?

There is no code, it is just a small estimate of the size of the files he is trying to make. The calculations are trivial.

You didn't type it all up yourself,did you? Maybe you just used M and don't cinsider that a code.

Hi;

OP = Original poster.

There is no code. This is not a program.

Agnishom

What is the meaning of OP?
Would you please give the structure of the code?

Each character of the 146 611 800  numbers is one byte of a text file. There are 6 characters per number:

9 x 146 611 800 ≈ 1.3 GB

Of course we did not get into compression because the OP never came back to discuss it further.

At first bobbym said :

So you are looking at a file that is around 1.3 gigabytes.

For six numbers the file is over 52 gigabytes and for 7 it is slightly more than 2 terabytes.

How can a file containing only 146 611 800 numbers be so large??

The 12 MB file might take 400 seconds that is about 7 minutes.

What do you program in?

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

It would take me many hours to upload them. My provider does not give me a lot of upload speed.
