Is there a general pattern to follow for creating columns for, say, Q and R?

If you read down the columns, the entries have a periodic pattern. The period of a column is half the period of the column to its left.

As an example for 3 sentence letters there are eight possibilities. So for the first letter we make 4 (8/2) T's and 4 F's. Then we make 2 (4/2) T's and 2 F's until we reach the end. Finally, we make 1 (2/2) T and 1 F down the column until we reach the eighth row.

I have a computer program that I've written for making truth tables that uses this algorithm for filling in the possibilities.
