Part 3: Doing some Math

Amusing easter eggs

• The abbreviation "Anko" in the Octashop receipt has four letters, like all the clue answers.
• "Wisemann" sounds like "wise man", which we'd hope a puzzle solver would be.
• Unless a "Wisemann grid" is significantly different than a regular one, the theorem is clearly false - there are two ways to color a grid as a checkerboard.
• The "lorem ipsum" text in at the bottom of the sheet seems to be slightly different from the usual. I don't know if this has any meaning - it's left out of the transcriptions, and could just be an artifact of the lipsum package in $\LaTeX$.
• The "math" starts at page 4, section 4.
