Section 3.20 says:
Given a set of FECs which are "aggregatable" into a single FEC, it is possible to (a) aggregate them into a single FEC, (b) aggregate them into a set of FECs, or (c) not aggregate them at all. Thus we can speak of the "granularity" of aggregation, with (a) being the "coarsest granularity", and (c) being the "finest granularity".
It should say:
Given a set of FECs which are "aggregatable" into a single FEC, it is possible to (a) aggregate them into a single FEC, (b) aggregate them into a set of FECs, or (c) not aggregate them at all. Thus we can speak of the "granularity" of aggregation, with (a) being the "coarsest granularity", and (b) being the "finest granularity".
Notes:
In the case of (c) the aggregation is not used, so there is no granularity.
--VERIFIER NOTES--
Not aggregating is a degenerate case of aggregation where a one-to-one aggregation mapping is used. Thus, the result is the "finest granularity".
