Talk:Racks and quandles

From Wikipedia, the free encyclopedia

A quandle should be defined in terms of a rack such that the duplication of axioms can be removed. --MarSch 11:16, 25 June 2007 (UTC)

I added some material on involutory quandles and the 'fundamental quandle' of a knot. It would be nice to have material on the Alexander quandle. A more glaring omission is that there's no discussion anywhere of the Wirtinger presentation of the knot group. John Baez 08:08, 28 June 2007 (UTC)
