摘要：An apparatus for displaying and performing a complete set of the sixteenbinary connectives in a two-valued notational system, the apparatus comprising at leastone device in which at least one combination of a plurality of symbols has been placed inat least one configuration. Each symbol has a shape selected to indicate a selectednumber of from zero to four components arranged with respect to the quadrants of aset of Cartesian coordinates. The shapes of the symbols have iconicity, eusymmetry, andframe consistency with respect to the quadrants of Cartesian coordinates and thealignments of the shapes of the symbols are symmetry positional with respect to theaxes of the Cartesian coordinates. The combination and configuration of the symbols arechosen so that the symbols can be positioned by a selected combination of flips,rotations, and counterchange operations to display and perform all sixteen binaryconnectives. The symbols are preferably letter-shaped symbols which can be readilyassigned a phonetic value.
