A good approximation using mathematical constants and a physical constant: gamma(0,577215665) < (PI/e)/2 = 0,5778636748954 gamma = (PI/e)/2 - alpha/((1+PI)*e) = 0,57721548319 alpha = Fine-structure constant = 0,0072973525643

I remember discovering it myself when I was trying to sum reciprocals, and noticed the graph looked a lot like ln x, so I let my calculator run all night working out the difference that was about 0.577.

Nice :-) Wondered if the log gave the infinitesimal generator of all rotations and an small experiment in Maple confirms. m is your matrix logarithm, then with(LinearAlgebra):MatrixExponential(phi*m) gives a generic rotation. For phi=1 your starting point half pi rotation (90º) is recovered and for phi=4 would be 2pi radians rotation. Satisfying!

Thank you very much for this. I was struggling with a similar problem for hours. I'm still trying to grasp it so I have a question: Would I be correct if I said that the matrix can be recovered unambiguously because: - The column vectors of A corresponding the pivot columns of A' form the basis of a column space of A - Thus, the other column vectors can be written as the linear combination of the basis vectors in EXACTLY one way.
