Dear Robert,

Thanks for the nice photo of 9_40! Can you add a note there saying in just a word or two where the picture was taken?

Robert -

By a classical theorem, an alternating link without "nugatory" crossings cannot be simplified. Hence the image you added, Noeudmongol.jpg, is an image of a 12-crossing link and cannot be an image of L8a14.



obviously, this is a big mistake


8 18

"8 18" is an alternating knot, while File:IMG 20180618 140044.jpg is non-alternating. AnonMoos (talk) 23:48, 5 August 2018 (EDT)

It's probably 8_19... AnonMoos (talk) 23:53, 5 August 2018 (EDT)
