 The Summary of \(\ast 211\) explains the definition as follows: “The members of D\( “P_{\epsilon} \) are called the segments of the series generated by P. In a series in which every sub-class has a maximum or a sequent [immediate successor (cf. \( ∗206 ) ] \), \( \text{D} “P_{\epsilon} = \overrightarrow{P}“C‘P \) \((∗211·38)\), i.e. the predecessors of a class are always the predecessors of a single term, namely the maximum of the class if it exists, or the sequent if no maximum exists. \( \ldots \) Thus in general the series of segments will be larger than the original series. For example, if our original series is of the type of the series of rationals in order of magnitude, the series of segments is of the type of the series of real numbers, i.e. the type of the continuum.” (PM II, 603)
