Quadruple Trefoil Knot

This is a quadruple trefoil knot that I had to manually create using an existing trefoil knot. This was created for a research project and not seeing one readily available, I decided to take my chances and try and create one as best as my abilities could do with Blender.

At this current time, I am not 100% sure this is what the quadruple trefoil knot actually looks like, but this is going based on what was described to me.

If it is not accurate, feel free to let me know how to improve or fix it.
