Looking for a bit bigger ? My Christmas crossnumber, inspired by the amazing @chalkdustmag conundrum, is here once again! nollakohta.fi/2018/12/jouluris

@petrilaarne This looks good, I'm going to print a copy to solve over Christmas. You should submit a puzzle to the @chalkdustmag puzzles page.

@mscroggs Here are all the right-angled triangles for question 12 of the advent calendar.

@ColinTheMathmo I've think I'm using \param instead of \epsilon (and set the value of \param in the preamble) because I've already swapped notation: it's typical to use \(\gamma\) for the parameter in question, but I noticed after draft 1 I was already using \(\gamma\) for something else. Let's hope I remembered this and used \param everywhere...

Aaarg, I'm using \(\epsilon\) and \(\varepsilon\) (for two different values) in the same equation. I fear it may be time to burn this laptop and start my PhD again from scratch.

\[\sqrt{\sqrt{9} - \sqrt{8}} = \sqrt{2} - \sqrt{1}\]
