The models of this last expression tell us which combinations of feature changes among the set <math>\{ \operatorname{d}u, \operatorname{d}v, \operatorname{d}w \}</math> will take us from our present interpretation, the center cell expressed by "<code>u v w</code>", to a true value under the given proposition <code>(( u v )( u w )( v w ))</code>.
The models of this last expression tell us which combinations of feature changes among the set <math>\{ \operatorname{d}u, \operatorname{d}v, \operatorname{d}w \}</math> will take us from our present interpretation, the center cell expressed by "<code>u v w</code>", to a true value under the given proposition <code>(( u v )( u w )( v w ))</code>.
The models of <math>\operatorname{E}q \cdot c</math> can be described in the usual ways as follows:
* The points of the space <math>\operatorname{E}X</math> that have the following coordinate descriptions:
<pre>
<pre>
<u, v, w, du, dv, dw> =
<u, v, w, du, dv, dw> =
<1, 1, 1, 0, 0, 0>,
<1, 1, 1, 0, 0, 0>,
<1, 1, 1, 0, 0, 1>,
<1, 1, 1, 0, 0, 1>,
<1, 1, 1, 0, 1, 0>,
<1, 1, 1, 0, 1, 0>,
<1, 1, 1, 1, 0, 0>.
<1, 1, 1, 1, 0, 0>.
</pre>
* The points of the space <math>\operatorname{E}X</math> that have the following conjunctive expressions:
<pre>
u v w (du)(dv)(dw),
u v w (du)(dv)(dw),
u v w (du)(dv) dw ,
u v w (du)(dv) dw ,
u v w (du) dv (dw),
u v w (du) dv (dw),
u v w du (dv)(dw).
u v w du (dv)(dw).

In summary, Eq.c informs us that we can get from c to a model of q by
