An Illustrated Classification of Knots.

2.4k Views Asked by At

Let me be honest here: I know very little about Knot Theory. I'm sorry.

I've a friend though, someone with no training in Mathematics at all but who is a huge fan of knots (for whatever reason), who knows even less than I do about it, apparently. Thus I'd like a book or something as a gift we'd both enjoy: an illustrated classification of knots up to some large order, say, like this:

which I found here.

Do you have any ideas? They don't have to be books.

Please help :)

I don't know about books... But if you think a piece of software can count as a gift, I suggest KnotPlot (http://knotplot.com/). It's a software package for creating, manipulating, and visualizing knots. The website has a bunch of nice examples.

The Knot Book by Colin Adams has a table of a lot of knots in the end, and is understandable for a non-mathematician who is interested in knot theory.

The Knot Atlas has various tables (of prime knots, of torus knots, of links, etc.)

The torus knot T(8, 3).

The hand drawings in A Topological Picturebook by George K. Francis are second to none.

From Steiner's Roman surface to Boy's surface.

Jim Hoste and Jeff Weeks published a paper with Morwen Thistlethwaite entitled "The First 1,701,936 Knots" that tabulates prime knots up 16 crossings. The two teams developed separate methods and worked independently to create this census.

I particularly like Figure 2 on page 35 (reproduced below), which shows nice projections of knots up to 7 crossings. These projections show symmetries of the knots.

Knots up to 7 crossings.
