Existence of complexes of clusters and complexes of isolated stars is the key to understand the cluster and isolated modes of star formation. Examples of such complexes in the LMC are considered. New kind of complexes with the circular shape or including arc-like structures is described, first of all in the LMC and NGC 6946. They may be of other origin than most HI supershells. The system of the giant stellar arcs (partiall spheres seen in projection) in the NE region of the LMC might be formed by GRB events, progenitors of which might be ejected from the massive nearby cluster NGC 1978. Otherwise the arcs might be results of cloud impacts, being concentrate at the NE side of the LMC because this side is leading in the orbital motion of the LMC. The strong arguments are given for the NE (and not Eastward) direction of the LMC movement. Also, the shock wave from a superexplosion might give the shape of the partial sphere to the facing surface of a nearby dense cloud.
