Yes, good point.  However I think the value the user passes in should
be the log base 2 of the ring size -- multiplying by an extra factor
of 2 is too confusing (who would ever expect to pass in 5 to get a
ring size of 64?).  Just ignore the value if it's less than 1 or
bigger than say 12 or something like that.
