     �rjan,
    
    Can you point at the place n the archive where this is discussed?

    I am surprised that anyone would use this method since logarithms were
    invented. Of course the tables for solving the triangle can be reduced
    to few pages if one does not care about speed. For example, the Russian
    set of tables MT-43 contains the "tables for solving Sumner's problem"
    that occupy 20 pages.
    
    Alex.
