4_1 is also known as "the Figure Eight knot", as some people think it looks like a figure `8' in one of its common projections.
In knot theory, a figure-eight knot (also called Listing's knot) is the unique knot with a crossing number of four. This is the smallest possible crossing number except for the unknot and trefoil knot. The figure-eight knot is a prime knot.
I followed this tutorial (originally shared through the IGKT France site, but the links changed) to try tying a 45 face globe knot, with 1.4mm nylon cord.

First drop perpendicular line segments from F to l2 and l4, and label the inter-section points by A and B respectively.
Proof First we observe that the intersection number is independent of the choice of surfaces.
Step 5 4. Barnacle Knot Buckle, technique with more options. 4.1. To start, decisions must be made. 4.1.1. a)Barnacle Knot--totally separate string.
In this lesson, we define some classical knot invariants. Section1. Minimum number of crossing points.
