Comment:
I went through most of everything once I have the references to the
algorithms. At this point, I do not have any plans to making any
(significant) improvements. I also agree with the philosophy of get good,
but maybe not perfect, code in and fix bugs as we come across them.
As a followup, we might want to consider adding in optional spkgs of those
other knot/link projects listed on Collins' webpage (e.g.,
[http://www.layer8.co.uk/maths/braids/ BraidProgramme]).
John, your changes look good to me. You should be able create isolated
components with something like this:
{{{
sage: B = BraidGroup(4)
sage: L = Link(B([1,3]))
}}}
There's also a more interesting example with two isolated trefoils in the
`plot()` examples:
{{{
sage: L = Link([[[-1, 2, -3, 1, -2, 3], [4, -5, 6, -4, 5, -6]], [1, 1, 1,
1, 1, 1]])
}}}
@fudlege I got your name from your Github page; I hope that was okay.
Thank you for working on this, and I hope you continue to contribute to
Sage.
