Thank you Struktor, for your question and Groundline, for your reply. Yes, I say, they are the same knot, simply presented differently. Struktor successfully demonstrates this by mapping the knot crossings and showing they may have the same tying order and may have the same projection. This knot invariant is known in the math literature as Conway 9* and Rolfsen 9_40. Groundline is not correct in distinguishing them. As presented they are both mats and they are also both utilizable for several applications such as, as fixed loops or stoppers. Seeing knots as cylinders when they may be used as cylinders obscures their more general character as polyhedral and geometric. Struktor further shows that both tying diagrams result in a single piece of geometry. This knot?s geometry may have several names including 1)a truncated triangular prism, 2)an elongated triangular antiprism, 3)a square antiprism with an added vertex or knot crossing. This knot is simply the completed circuit of the True Carrick Bend.
