It seems like the prior statement is incorrect. I suspect what this should say is [[10_124]] and [[8_19]] are the only torus knots which are also almost alternating. See page 108 in the Encyclopedia of Knot Theory. Confirmation of this is that [[3_1]] is the pretzel knot P(1,1,1), i.e., the right-handed trefoil. It looks like [[5_1]] is a pretzel knot also, and so on, i.e. [[7_1]], [[9_1]], and should include the Hopf link and the Solomon link etc. These are torus knots/links also. |
