The goal:The goal:

Create a format that would consist of all the Create a format that would consist of all the possible combinations of several values.possible combinations of several values.

For example:

"M1TM" - "M1TM" = "Missing to 1+ to Trace to Missing"

The usual way of accomplishing The usual way of accomplishing this:this:

Typing all the combinations into a format. Typing all the combinations into a format.

When there are only 4 or 5 possible values When there are only 4 or 5 possible values in 2 positions, this is no problem.in 2 positions, this is no problem.

The problem:The problem:

We are starting with 7 values, in each of 4 We are starting with 7 values, in each of 4 positions. This results in 7 * 7 * 7 * 7 = positions. This results in 7 * 7 * 7 * 7 = 24012401 combinations. The problems include: combinations. The problems include:
