Center dot is not at all uncommon in strictly mathematical context, and for any kind of multiplication-like operation. I've been doing math for far longer than 40 years, and I never encountered the * for multiplication of ordinary numbers before I first began programming with FORTRAN (my first computer language after assembly) in 1959. The * is, however, and long has been, used in mathematical discourse to denote an arbitrary operation in a group or monoid or whatever -- precisely because it's NOT the usual multiplication sign for numbers.
