Smart scrambling of digits onto pyramid to match edge-endpoint equations
by jonah.luo •
The problem is about filling numbers 1 – 11 into all vertices and edges of a tetrahedron, and the numbers assigned to edges equals the numbers assigned to its two endpoints.
(It’s not really scrambling BUT looks like scrambling until you know or find the equalities on edge-endpoint numbers). The problem is interesting — but you got to know where to look, and how to search for a solution!
