Suppose that $A$ is a finitely generated abelian group with even rank and without $2$-torsion. Does there exist a compact symplectic $6$-manifold $(M,\omega)$ such that $A$ Is isormorphic to $H^{3}(M,\mathbb{Z})$? (The reason for excluding $2$-torsion is the fact that a (closed, orientable, connected) smooth $6$-manifold without torsion in $H^{3}$ has an almost complex structure hence a hope to be symplectic). Edit 1: Someone pointed out to me a very simple solution to the original question. Let $2k = rank(A)$, by Gompf we may find a compact symplectic $4$-manifold N such that $\pi_{1}(N) = H_{1}(N) = \mathbb{Z}^{k} \oplus T$ where $T$ is the torsion sub-group of $A$. Then by the Kunneth formula $H_{3}(N \times S^2) \cong A$. We can even (by finding appropriate algebraic surface with $\pi_{1} = \mathbb{Z}^{k} \oplus T$) stay in the category of projective algebraic 3-folds). **Question** Same question as above but we insist $\pi_{1}(M) = \{1\}$.
