I have written a macro

The purpose is to caculate all 4499879580584837311451522624 combinations

(14 x 14 x 14 x 14...14 (14^25)

However, I realize with my computer's speed, it probably is impossible to EVER finish running that many combinations.

Therefore, I am just wondering if I can do anything to make the code more efficiently? or it's just impossible to test 14 to the power of 25 combinations with a normal desktop computer???

To provide a better idea, I have uploaded the workbook macro I created

http://www.mediafire.com/?0d62kmerzp8c3g2

Below is the backgroud to the workbook uploaded:

To me, this is pretty much an IMPOSSIBLE-TO-SOLVE My professor gave

as a bonus question for the term.

The question is:

There are 25 Teams in Sheet "Table" in the workbook (Team A ~ Team Y)

Each team, there are 14 configurations

(eg. Team A-1, Team A-2...Team A-14)

Team B-1, Team B-2...Team B-14....and so on..)

In every game, all 25 teams picks a confiugation to play.

eg.

Game1: Team A-1, Team B-1, Team C-1... Team Y-1

Game2: Team A-1, Team B-1, Team C-1... Team Y-2

Game4499879580584837114515226624: Team A-14, Team B-14, Team C-14....Team Y14)

Out of all the games (combinations), he said there are few games with 5 or more players NOT playing at all.

Our job is to figure out which players they are.

Hence all the FOR/LOOP in the macro to test out all the combinations. Any more efficient way?

Thanks
