 A rectangle Around A rhombus (Posted on 2008-04-14)
A rectangle ABCD is circumscribed around a rhombus AECF. The long sides of the rectangle coincide with two sides of the rhombus. Also, the rhombus and the rectangle share a common diagonal AC.
```B       E               A

What are the smallest dimensions when all the lengths AB, BC, AE, AC and EF are integers?

Find a parameterization of all such integral rectangle/rhombus pairs.

I've just come on-line and caught it.  I've something lengthy to consider here.

I would observe however that BC is quite important if ΔBCE, ΔABC and ΔEFX, er, X? CX=FD, are to be Pythagorean triangles.

Let me see some other thoughts before I make my post.
