Hedgehog got a problem about a tetrahedron during his geometry test.

He stared at it for forty minutes. There was fog outside. Then he wrote the solution on the back, accidentally encrypted the jam into the symmedian dot, and handed in the work.

The teacher wrote in red pen: "Unconventional, but correct. 5"

The jam has disappeared.
