Snap Cube Puzzle: Snap cubes have a post on one side, and holes (into which a post can fit) on the other five sides. How many ways to build a 2x2x2 cube out of eight snap cubes such that (1) the entire structure is connected, and (2) all the posts are in the interior – no posts sticking out of the surface? (All the different structures look the same from the outside; the difference is in the orientation of the eight posts internally.)
@jsiehler Okay, that blog entry as promised: http://tpfto.wordpress.com/2019/04/24/on-constructing-an-elliptic-function-from-its-zeroes-and-poles/
What's the "most scalene" right triangle – that is, how should the edges be proportioned so that the minimum difference over all pairs of sides is as large as possible? Let's assume we've normalized so that the hypotenuse is 1 unit.
(If you enjoy the answer for right triangles, also try the problem for triangles with a 120-degree angle.)
