I have been working through the standard list of small prime knots, with the aim of creating elegant and, where possible, symmetric three-dimensional realizations. Here you will find my versions of the knots described in terms of 2D diagrams, lists of coordinates of points along the curve, Fourier series, .scad files and .stl files. I follow the nomenclature used in Knotinfo and Knotserver.

Many small knots have symmetric three-dimensional realizations.
I have therefore sought to offer these when possible.
On the pages devoted to individual knots, I name symmetries
(D_{2}, D_{4} etc) when I have found them.
Note that a knot may have various symmetries witnessed by different
realizations. By
"symmetry" here what I really mean is a conjugacy class of finite
subgroups of the isometry group of S^{3},
but I think most of us would prefer to have a list of descriptions relating
to the rather arbitrary names I have used:

All knots with D_{2}(r) symmetry are
strongly invertible.
Of the knots here, 4_{1}, 6_{3}, 8_{3}, 8_{9},
8_{12}, 8_{18} and 12a_{1202} are
fully amphichiral;
8_{17} and 15331 are negatively amphichiral. I believe that 15331
is prime.
