By the by, is there a reason you are skipping every other variable
(forval o=2(2)`t')? Note that the dimensions of the matrix that will
result due to this procedure will be [kx3] where k is half the number
of variables in `rest', i.e., the total number of variables less one.

To every ω-consistent recursive class κ of formulae there correspond
recursive class signs r, such that neither v Gen r nor Neg(v Gen r)
belongs to Flg(κ) (where v is the free variable of r).
