TopNewestA star doesn't have to be 5 pointed. It could be 4 pointed, which can be done here.

Let the center dot be 1, and going clockwise the rest of the dots are 2, 3, 4, 5. Then draw 1 to 3, thence to 5, thence to 1, thence to 2, thence to 4, thence back to 1. You have your 4 pointed star.

:) but you have to use all the dots. Your answer might be right, but that's not what I was looking for 😂
