There is an old puzzle that asks how to wire three three-way
switches in such a way that each of them can switch on or
off a lamp.
I cannot find the solution - is there a web page about this?

Apparently, 615000 of them.

(1) This is NOT the puzzle about the three switches that you find
everywhere.
In fact, the wiring is not trivial.
(2) The link does not give the 3x3-way switch solution; only the easy
2x3-way plus 1xfour-way solution.
