I did not intend to suggest that quantifier shifts
are the only fallacies you commit.

Steps 1 through k.
Steps 1 through k have a counting-order
(total order, each cut is a step, each step is a count)
which begins at 1 and ends at k, whatever is.
Without ending somewhere, they're not the first kind.

Steps 1 through 8 have a counting-order
(total order, each cut is a step, each step is a count)
which begins at 1 and ends at 8.
Without ending somewhere, they're not the first kind.

As long as X's are available,
the transpositions have a stepping-order
(total order, each cut is a step)
which begins somewhere and ends somewhere.
Without ending somewhere, they're not the first kind.

All fractions of the matrix do NOT have a stepping-
-order (total order, each cut is a step)
which begins somewhere and ends somewhere.
Without ending somewhere, they're not the first kind.

All fractions, the collection of, is the second kind.
d/n gets an x from i/1 where i = (d+n-1)*(d+n-2)/2 + n
All O's disappear.

First kind ≠ second kind.
