However the exam papers of the GCSE sometimes had a choice of questions, designed for the more able and the less able candidates.

English: The sixteen logical connectives ordered in a Hasse diagram. They are represented by: logical formulas; the 16 elements of V 4 = P^4() Venn diagrams; The nodes are connected like the vertices of a 4 dimensional cube. The light blue edges form a rhombic dodecahedron - the convex hull of the tesseract's vertex-first shadow in 3 dimensions.
For example, NPST non-past is not listed, as it is composable from N-non-+ PST past. This convention is grounded in the Leipzig Glossing Rules. [2] Some authors use a lower-case n, for example n H for 'non-human'.

The self-dual connectives, which are equal to their own de Morgan dual; if the truth values of all variables are reversed, so is the truth value these connectives return, e.g. , maj(p, q, r). The truth-preserving connectives; they return the truth value T under any interpretation that assigns T to all variables, e.g. ∨ , ∧ , ⊤ , → , ↔ ...
