Directions are:

Up down
Right left
Front back

When we move through space we are moving in a 6 directional space grid
in only 3 of these directions.

But here on the three dimensional earth grid it
is 6 directions ---
North,South,East,West,Skyward,Earthward. ;-)

Or on the earths open seas' 3 dimensional grid --

Port,Starboard,Bow,Aft,Skyward,Davy Jones's locker.

Those are three directions and each direction has a positive or
negative coefficient. However, 2-forms in 4 dimensions do have 6
directions.

In R^3, all k-forms can be embedded in R^3. The 0-forms and 1-forms
can be mapped directly to constants and vectors. 2-forms, such as
rotations, have 3 dimensions, (dx^dy, dy^dz, dz^dx) and can be mapped
to vectors (dx^dy -> dz, dy^dz -> dx, dz^dx -> dy), and 3-forms, like
volumes, can be mapped to constants (the coefficient of dx^dy^dz).

In R^4 and higher, there are k-forms that cannot be embedded into the
base dimension. For example, the 2-forms in R^4 are 6-dimensional:
dx^dy, dy^dz, dz^dw, dw^dx, dz^dx, dw^dy.

But sometimes, the directions go round and round (polar coordinates),
or form open curves (hyperbolic coordinates).
