Imagine, if you will, that you wish to print (but first, draw) an E8 lattice in honour of theoretical physicist Antony Garrett Lisi.

 

Here's what it looks like, modest and unassuming that it is...

Unless you wanted the fun of drawing it yourself... 🙂  you can download this svg file.

I had a quick look and it seems to be well structured for ease of coloring etc.

I'm late, but here is my easy-to-make version.

var d = app.activeDocument.artboards[0].artboardRect;
var paths = app.activeDocument.pathItems;
var circle1 = paths.ellipse(d[3]/2+250, d[2]/2-250, 500, 500);
var polygon1 = paths.polygon(d[2]/2, d[3]/2, 250, 12);
polygon1.rotate(15);
var points1 = polygon1.pathPoints;
var group1 = app.activeDocument.groupItems.add();
for (var i = 0; i < points1.length; i++) {
  for (var j = 0; j < points1.length; j++) {
    var line1 = paths.add();
    var points2 = [points1[i].anchor, points1[j].anchor];
    line1.setEntirePath(points2);
    line1.moveToEnd(group1);
  }
}
var group2 = group1.duplicate();
group2.resize(70.7, 70.7);
group2.rotate(15);
var group3 = group2.duplicate();
group3.resize(73.2, 73.2);
var group4 = group3.duplicate();
group4.resize(70.7, 70.7);
group4.rotate(15);
