A pretzel knot is formed from a planar unlink of two components by joining the two components with parallel twisted bands. For instance, P(-2,3,7) is formed by adding bands with -2, 3, and 7 half twists as illustrated below. The diagram presents P(-2,3,7). (This knot is also 12n242.)
The data through 9 crossings was provided by Diaz and Manchon , who checked that it is correct with respect to orientation.
