  We consider frames in a finite-dimensional Hilbert space where frames are
exactly the spanning sets of the vector space. A factor poset of a frame is
defined to be a collection of subsets of $I$, the index set of our vectors,
ordered by inclusion so that nonempty $J \subseteq I$ is in the factor poset if
and only if $\{f_i\}_{i \in J}$ is a tight frame. We first study when a poset
$P\subseteq 2^I$ is a factor poset of a frame and then relate the two topics by
discussing the connections between the factor posets of frames and their duals.
Additionally we discuss duals with regard to $\ell^p$ minimization.
