An Eccentric Billionaire's Riddle of Fours

The Puzzler


RAY: This puzzler is from my horticultural and mathematical series. It was sent in by Daniel Reiss. And, of course, I couldn't resist the temptation to mess with it a little bit.

Here it is.

An eccentric billionaire decided to interview landscapers for his newly constructed estate. Part of the interview was a simple test. He said:

"Four is my lucky number. I made my fortune working four hours a week, just like those two knuckleheads on Car Talk!

"So, I want every tree and bush and shrub you plant to be in groups of four. Got it? But in addition, I want each of these four things that you plant, to be the same distance from one another.

"For example, if you plant four rhododendron, I want them all to be equidistant, i.e., each one is the same distance from each of the other three."

The question is, can it be done?
