Query: On the Artal--Carmona--Cogolludo construction   We derive explicit defining equations for a number of irreducible maximizing
plane sextics with double singular points only. For most real curves, we also
compute the fundamental group of the complement; all groups found are abelian.
As a by-product, examples of Zariski pairs in the strongest possible sense are
constructed.
