   I have read in several papers, books, etc, that Euler 
proved a famous theorem in 1752 (or whenever), showing that
for any two orientations of the same object, that there
was a single rotation about a single axis that would 
transform one rotation to the other.

   Although the result is mentioned, the actual formula/
algorithm for calculating the axis of rotation and rotation
angle is never given!

   Does anybody have this formula handy?
