2 segment being two points on the frame. There are n endpoints on the northern edge of the frame and m on the southern edge. Lines exposed to Ž. the western edge and only those carry either a blob, or box I. For Ž. example, the diagrams in Fig. 1 are 7, 7-diagrams. In a diagram, any line which begins and ends at the same edge is a ‘‘loop’’; all other lines are ‘‘propagating lines.’’Thus the leftmost propagating line, if any, carries a blob or box. A ‘‘heap’’is a loop exposed to the Ž. opposite edge, together with any loops nested within it. The set of n, m-Ž. diagrams is denoted D n, m.
