- This is a consequence of a fact established earlier, namely, that any set C formed by choosing one formula from each Sj must contain some formula πB and its conjugate, where B is a Boolean atom of X.
- 1982, Krister Segerberg, Classical propositional operators, page 55:
- If C is a Boolean atom, the claim is obviously true.

- A list is a bit vector if each of its members is a Boolean atom.
