The Lehmer Matrix and its Inverse

It's strange where things can lead.  I wondered if a matrix of consecutive integers had a special name in standard mathematical usage.   I couldn't find such a name, but I did find a few with special names, including one called the Lehmer Matrix.   Before I knew what was happening, I'd created a Mathcad worksheet implementing the Lehrer Matrix and its inverse, which has an explicit formula.

 

The worksheet is attached.  I can't check it properly because I'm about to run out of my 30-day trial period and lose both symbolics and programming.

As requested, Vladimir, plus (very slightly) amended worksheet ... please ignore the last page, I was just playing.

 

Oh, and a link to the Wiki page on the Lehmer Matrix: https://en.wikipedia.org/wiki/Lehmer_matrix
