This pattern I stumbled upon when I was playing with hexagons and octagons. After a bit of massaging, I ended up with an outline of the candlestick (here it is the white 3-layered pattern between the stars). In the original play, the 3 triangles were part of a hexagon that intersected with the others. From there, I connected 6 together to make large hexagons with octagons in the corners. I was surprised at first that I could make 3 into the triangular shape and more surprised that a small triangle exactly fit inside it. After some thought, it made more sense.
Image a loop of hexagons with octagonal spacers between them. Then connect each of the hexagons with a rectangle to other hexagons from other loops. Voila, this tiling with less decoration. The reason for the triangle exactly fitting is a little more involved. You have to take the loop of polygons on the left and separate the rhombus with two perpendicular lines. The bottom perpendicular is easy--going from a 4-sided figure to an 8-sided. The top perpendicular is trickier--going from a 12-side figure (the square and triangle make the 150 degree angle of a 12-sided polygon) to a 24-sided polygon (the 135 and the 60 of the octagon and the triangle make 195 which is the exterior angle to 165, the angle of a regular 24-sided polygon).
I'm not sure about how close the pentagons are to each other. It looks like they touch at the vertices... I may have to get a pencil and paper to check it out....

The math involved in all this makes my head hurt, but I like them all.
