TITLE: Crafting Suspension Spectra
QUESTION [7 upvotes]: There is a theorem by Hopkins and Smith which states that for every $n > 0$ there is an ideal $I_n = (v_0^{k_0}, \dots, v_n^{k_n})$ such that there exist a spectrum $X_n$ with the following homology:
$$ BP_*(X_n)=BP_*/I_n.$$
I was wondering if it was possible to have a similar but more detailed result.
Is there, for every $n$, an ideal $I_n = (v_0^{k_{0,n}}, \dots, v_n^{k_{n,n}})$ such that:
1)  For every $i$, the limit of the $k_{i,n}$ goes to infinity when $n$ goes to infinity,
2) There exist a suspension spectrum $X_n$ with $ BP_*(X_n)=\Sigma^{d_n}BP_*/I_n$, for a natural number $d_n$
3) The $d_n$ don't go to infinity when $n$ goes to infinity.
if it's not possible to satisfy 1,2,3, what about just 1,2? 
Thanks!!!

REPLY [2 votes]: For large $i_0,\cdots,i_n$ we can realize $BP_\ast/(v_0^{i_0},\cdots,v_n^{i_n})$ as the $BP$-homology of a finite spectrum $S/(v_0^{i_0},\cdots,v_n^{i_n})$. This follows from Devinatz-Hopkins-Smith. Suspending a finite spectrum enough times gives a suspension spectrum. This means that there is some space $X_n$ such that $\Sigma^{k_n} S/(v_0^{i_0},\cdots,v_n^{i_n}) \simeq \Sigma^\infty X_n$ for $k_n\gg 0$. I'm not sure how to address the question about the limit of the $k_n$'s.
