If you want more, then here you can download the tables of all 352,152,252 prime nontrivial knots with up to 19 crossings.
The tables are plain text CSV (commaseparated value) files which you can load into a spreadsheet and/or process with a text editor, and have been compressed with bzip2. The fields include:
name: The name of the knot, using a naming scheme specific to these tables. An example name is 12nh_137. In general the name is of the form c[an][tsh]_k, where:
The torus and satellite knots are sorted according to their structure. The hyperbolic knots are sorted roughly by volume, but take care—although the distinctness and hyperbolicity of the knots are proven using exact computation, the final sorting order is based on approximate volume computation only.
knot_sig: The knot diagram, expressed as a native Regina knot signature. An example signature (for the knot 7ah_5) is habcadebcfgedgfvvbZa. Knot signatures uniquely identify a diagram on the 2sphere up to relabelling and/or reflection. In Regina 5.2 or later you can reconstruct a knot from a signature through the GUI, or by calling Link.fromKnotSig() in python.
dt_code: The knot diagram, expressed as an alphabetical DowkerThistlethwaite (DT) code An example DT code (again for the knot 7ah_5) is fdgeacb.
dt_name: Identifies the knot in other online databases such as Knotinfo and Knotscape (this field only appears in the tables for ≤ 12 crossings). This field uses the DowkerThistlethwaite naming convention, where knots are numbered according to their minimal DT codes.
structure: Gives the full structure of a torus or satellite knot (this field does not appear in the hyperbolic tables). An example is Trefoil[3/2], indicating a satellite formed by inserting the rational tangle 3/2 into the double of the righthand trefoil. See the paper below for a full explanation of what the various structure descriptions mean.

Here you can download additional census files that are too large to ship with Regina. You can also find the standard files that are shipped, in case you have an older version of Regina that did not include them.
You can open each of these data files directly within Regina. Each file begins with a text packet that describes what the census contains and where the data originally came from.

Knot and link complements  
Christy's collection of knot complements (≤ 11 crossings) and link complements (≤ 10 crossings)  Collected by Christy Shipped with Snap 1.9 
hypknotlinkcensus.rga  132 
In older versions of Regina, Christy's collection used to be called “hyperbolic knot / link complements”; however, it also contains some (but not all) nonhyperbolic cases. It also contains the duplicate Perko pair.
Because the proof involves computation, there is a fair amount of supporting data, including the 23tetrahedron triangulation of the WeberSeifert dodecahedral space and its 1751 standard vertex normal surfaces. This is stored in a Regina data file, which you can download here:
