are obtained by a single crossing change in a minimal crossing diagram of a given knot, whereas the second generation predecessors are obtained by single crossing changes performed Vans Toy Story Old Skool on minimal diagrams Vans Hi Sk8 Pink

of the first generation predecessors, etc. Diao et al. 23 showed that starting from any minimal diagram of a given alternating knot, one always obtains the same set of first generation predecessors due to that fact that any such diagram is related to any other by a simple transformation known as a "flype". For non alternating knot types, different minimal diagrams can produce different sets of first generation predecessors.

e more precise, in Ref. 22 the objective was to distinguish predecessors of various generations arising from the classical knot presentations. The first generation predecessors are the knot types that Vans Grey Shoes

Finally, the third generation predecessors arising from the 31 knots that have come from 51 or 52 subknots are also unknots. Fig. 2D shows the disk matrix of the KnotPlot configuration of the 75 knot. We see that the 31, 51, and 52 knots also form first generation subknots. First generation subknots can be recognized easily in the disk matrices as having territories that can be accessed directly from the territory of the global knot while advancing radially toward the center of the matrix.

diagrams chosen and therefore the set of predecessors for non alternating knot types is not a topological invariant. For this reason, we focus our analysis on alternating knot types that do not have non alternating predecessors. The knot 75 was specifically discussed by Diao et al. 23 and was shown to have 31, 51, and 52 knots as first generation predecessors. The second generation predecessors arising from a single crossing change in minimal diagrams of 51 knots are 31 knots, those arising from 52 knots are 31 knots and unknots, and those arising from 31 knots are always unknots.
