As expected, the number of output knots decreases as the cutoff parameter NF increases, until only the truly distinct knots remain. To see how knots with crossing numbers up to 12 are shown distinct, click . (Technical remarks: For NF=15: Memory needed is about 20 MBytes, CPU time is about one month, computer language used is f77, the program is run at the Orion machine at the Deutsches Elektronen SYnchrotron D.E.SY. at Zeuthen, Germany).
