Boolean hypercube
Every row of a truth table is a corner of a cube, and neighbouring corners differ in one variable. Where two neighbours are both 1, that variable doesn’t matter, so the pair merges into a simpler term: the same idea a Karnaugh map draws flat.
Expression
Up to four variables. Same syntax as the gate simulator.
Try
Fig. 1
The cube of F
Drag to turn, scroll or pinch to zoom. Click a corner to read its row.
Table 1
Groups of adjacent 1s
Each group is a sub-cube whose corners are all 1: a pair is an edge, four make a face, eight a cube. Pick one to highlight it.
