How to reduce the number of tables?

Hi everyone!

I have a big problem:

If there is a set A={1,2,3,...,47,48,49} there are 49 elements, if we choolse randomly 6 numbers what is probability?

If we generate all of these combination and we will have 13983816 combination.

We want to put these in a table and add six column it will be (12-COLUMNS X 13983816-ROWS) then the number of rows will be reduce.

I have build some tables with a sample 2-elements from 9.

The first table is main and the other tables are the table in wich all of these combiantion find.
