| Besides 0 and ~0, two other dual relative terms have been called
| terms of second intention. These are simply S(~0) and V(~0).
| The relative S(~0) or (~0,) is also written 1, and is called
| unity, or "identical with". It is defined by the equations
|
| (1)_ii = 1, (1)_ij = 0.
|
| That is,
|
| 1 = (A:A) + (B:B) + (C:C) + etc.
|
| The relative V(~0) is written ~1 or `n`, and is called "not",
| or "the negative of". It is defined by the equations
|
| (~1)_ii = 0, (~1)_ij = 1.
