There are many ways to represent a knot in a square grid, even when we wish to reveal all its existing symmetries. For this particular bend ( M. B27), Miles himself shows a pattern which occupies a 9 x 9 cell area, more complicated than the 7 x 7 I show here ( see Symmetric Bends, p. 95).
The Pretzel-to-Pretzel bends, perhaps because they seem more complicated than necessary, have not been explored yet - and, of course, they have not been tested. However, with the advent of very slippery materials, they might find a place in the knot tyer s toolbox it was never envisioned they would.
I also attach a KnotMaker .km file of this bend. The reader is advised to watch the "Animated" knot in slow motion. ( Go to the "Indvidual ropes" window, and "Animate". We can see the path of both ropes, been traced from the Standing End to the Tail End, or any one of them separately, by checking both "rope 1" and "rope 2", or one of the two.)
