So I had a thought that the slashes might not mean division, but instead that they're alternatives. I noticed that there are THREE sets of numbers separated by commas. Which means that if these were points then they would be points in 3d space (not 2D like the triangles that have been floating around on this thread). So I found a tool to plot points in 3d space (
http://hotmath.com/learning_activiti.../3dplotter.swf) and assumed that the slashes meant that the coordinate could be either number. That process would give us 8 possible points in a box pattern.
I can't figure out how to insert it into my post so I included the screenshot as an attachment.
(NOTE: I plotted the points at 1:1000 scale to make them fit on the graph better, according to geometry this will not affect the shape at all.)
