ARCA - a notation for displaying and manipulating combinatorial diagrams
Meurig Beynon · Warwick Research Archive Portal (University of Warwick) · 1986
ARCA is a programming notation which was originally developed with the computer animation of a class of diagrams studied by ARthur CAyley [sic] in mind. It is presented here as an archetypal example of a "definitive notation", in a sense explained in a previous paper by the author. This paper is an informal introduction to the principles of ARCA and the ARCA system, and includes some tutorial examples.
