Speaking about infusion - What's the best way to arrange the pedestals around the table? I often see three per side in LPs and I think, that's wrong.
When you examine the recipes in the thaumonomicon, there are four possible locations for ingredients in the corners and two on each side, a bit outside of the squares. It seems there are twelve positions for ingredients arranged in a circle.
So I put four pedestals in the corners with one block of space between them and the edges of the altar. The remaining eight are one knight-move (chess) away from the corner-pedestals.
That way you can arrange the ingredients in an equilateral triangle, square, hexagon and octagon. Pentagon and heptaon are a bit off, but not much.
