- We analyze some posets involved in forcing constructions for dense ideals, showing that the Anonymous Collapse and the Dual Shioya Collapse are equivalent for collapsing a large cardinal to $ω_2$. We also give a somewhat simplified construction of a normal ideal $I$ on $ω_2$ such that $\mathcal{P}(ω_2)/I \sim \mathrm{Col}(ω_1,ω_2)$.
