It seems that my last email got chopped so I am resending it, sorry...
Q4. "Indices" of various kinds proved to be useful in different areas of mathematics, e.g. linear algebra.
Q5. I need expressions of the type \sum_{j=1}^n a_j b_j for an unspecified symbolic value n and quantities a_j and b_j *labelled* (rememberring that _indexed_ is already copyrighted) by j in this range.
I have the same type of concern.
