 FMMD analysis creates a hierarchy $H$ of {\fgs} where $H \subset \mathcal{FG}$.

-We can define individual {\fgs} using $FG$ with an index to identify them and a superscript

+We can define individual {\fgs} using $FG^{\alpha}_{i}$ with an index, $i$ for identification and a superscript --- or $\alpha$~level (see section~\ref{sec:alpha}) ---
+to identify the hierarchy. 
+For instance the first {\fg} in a hierarchy, containing base components only
 i.e. at the zeroth level of an FMMD hierarchy, would have the superscript 0 and a subscript of 1, i.e. $FG^{0}_{1}$.
