@andrewkirk posted the following:
The symbol should be a diagonal stroke through (not next to) a vertical stroke, meaning "does not divide".

The symbol should be a diagonal stroke through (not next to) a vertical stroke, meaning "does not divide".

Doesn't seem to be an error. \not{|} works, but in that post, the braces are missing:

$\not{|}~~~$ vs $~~~\not|$

Even \cancel{|} works: $\cancel{|}$
