Where does this particular method for computation of the Alexander polynomial come from? I believe I followed the method correctly, but depending on the two columns eliminated, I get different determinants.

This is the method given by Alexander in his paper, except the article neglects to mention that one should "renormalize" at the end (something Alexander obviously realized), since there is ambiguity (depending on columns eliminated, as you've seen, the result can differ by multiplication by \pm x^n. Anyway, I will add the statement. --Chan-Ho (Talk) 00:31, 13 April 2006 (UTC)

[edit] Example of skein relation computation for Conway poly

Moved from article:

(reader's note: This is a terrible example. The article would be much improved by a picture of a simple 3-4 crossing knot and then the step-by-step calculation of the Alexander polynomial! ) --—The preceding unsigned comment was added by 128.101.126.230 (talk • contribs).

This comment is referring to the section on the Conway polynomial which ends by saying see skein relation for an example of a computation. The point is well taken. I will try to get to it sometime. --Chan-Ho (Talk) 11:29, 9 May 2006 (UTC)
