Further Towards a Triadic Calculus

I have tried to follow closely the organization, the material, and even the wording[1] of that paper wherever possible, though further developments have made many of the conclusions reached here quite different from those in QPR 84. Major points of departure in the present paper are in the graphical notation, which makes the ordering of the elements of a triada much more visible and manipulable geometrically, and in the two additional restrictions imposed on complex triadas involving interfaces and internal connections. The section on computer-aided triada logic development is also entirely new.
