+    basis_of_h22(v::NormalToricVariety; check::Bool = true)
+
+Computes a basis of the cohomology class $H^{2,2}$. This method requires
+a toric variety whose dimension is at least 4. In addition, the variety in
+question must be both complete and simplicial. Since it can be computationally
+very demanding to verify completeness of toric varieties, the optional argument
+`check` can be set to `false` to skip those tests.
+
+# Examples
+```jldoctest
+julia> F3 = hirzebruch_surface(NormalToricVariety, 3)
+Normal toric variety
+
+julia> h22_basis = basis_of_h22(F3*F3, check = false);
+
+julia> length(h22_basis) == 10
+true
