Consider, further, [[!teximg Error: <a href="./474e6b9ba137423020dc0f53fd718d89.log">failed to generate image from code</a>]].
This, in mathematical terms, may be called
cancellation. It differs from [[!teximg Error: <a href="./6149ea7e1a0c121f0706af7ce938e568.log">failed to generate image from code</a>]],
which may, in mathematical terms, be called
