Right, and that includes the space between the point you think is the first point of the open interval and the end point of that interval
Between [0, 1] and (0, 1] there is nothing, there is not a spot or point of the interval.
Regards, WM
Right, just a missing 0.
But that doesn't mean there is a lowest most point in (0, 1] as any point you might want to call it will have another point between it and 0.
Note, I said between the point your THINK is the first, there is no such point, and thus you are agreeing to that fact.
You can only have a first point in the open interval if the interval has only a finite number of points, but it has an infinite number of points, so there is no space for a first.
