Our final piece of today's delicious cake may at first glance seem more like a cookie. But… hold on. Isn't computer science the application of mathematical science to machines built from rare earths, metals and liquified dinosaur remains? (The things that make up for our lives?) I would say yes.

Hence, the following discourse in mathematics is not only incredibly enjoyable. No, those unfamiliar with the topic will come away significantly more enlightened.

But what is it about?

It's about one of the most powerful diagrams in modern mathematics, which directly influences a range of topics that matter to us every day: Group Theory, Combinatorics, Error Correction. (And a few other topics you might rarely encounter, like Sphere Packing.)

Without giving anything away, this upcoming video by Alex - the creator behind the YT channel @AnotherRoof - definitely belongs in the top 100 of personal must-see videos. With a duration of 45 minutes and 48 seconds, it provides just the right depth of insight.
