Here's the slightly longer version of why I'm asking that question.
Ok, if you look at the image below there are three graphs. The one on the left, as badly as I drew it in MS Paint - should be visibly a pentagram. The pentagram is well known as a symbol in various religions. However, I was bored and idly thinking, and the pentagram has an interesting mathematical property it shares with only one other graph, the one on the right (ok there are 2 graphs on the right, but mathematically speaking they are equivalent - just different ways of drawing the same thing). A quick description of the math is at the bottom. Anyway, I was wondering if this property was one of the reasons it was initially adopted as a religious symbol (Ok it's a star, but there are lots of way's of drawing stars) and if it was, if the other graph was also adopted as a religious symbol.
And yes.. this might just be me being so bored that I'm looking for patterns where there are none

(The mathematical property is that they are the 2 simplest graphs you can draw where no matter where you move the nodes (dots on the picture) or bend the edges (the lines) at least one of the lines must always cross another. Without getting to much into the math, the reason these are the 'simplest' is because any other graph that shares that must have crossing line(s) must also contain one of these 2 graphs. If you want to search for it, look for Kuratowski's theorem ).
