e. The set of coordinate functions, also referred to as "basic" or "simple" functions", has a cardinality of n and is denoted in the following ways:
−X = (X :> B) = {f : X :> B} = {xi : X->B}.
<p><math>\underline{X}^{\odot\!\to} = (\underline{X} ~\odot\!\!\to \mathbb{B}) = \{ f : \underline{X} ~\odot\!\!\to \mathbb{B} \}.\!</math></p></li>

−2. The sign "xi", read or understood in a propositional context, can be interpreted as denoting one of the n "features", "qualities", "basic properties", or "simple propositions" that go to define the n dimensional "universe of discourse" X[], also notated as follows:
