Because different naming conventions are available here (including the classical system and the DT system) the rank of the names is also given. For instance, the knot 9_9 is the 45th knot on the table using classical naming system. It is knot -9a_33 in DT notation, which is 69th knot in the DT table of knots (ignoring the sign). Our basic naming convention uses the classical names through 10 crossings and using the DT names for 11 crossings.
By downloading these ranks, the user can sort the table using any of the conventions.
