>>977610Yeap, I worked it out like 1 plus 4 and consecutively 2 plus 3 were on the same side, if you get what I mean. Here, have a look at my scribbles, maybe that makes it clear.
That way I got all the way to "step 8" (16 steps total, but steps 9-16 would be mirrored) before running into a illegal configuration.
Does JBSS have an option like don't let the lines cross or something?
