Abstract
Attempts to measure structural parameters of superclusters are described. Catalogues of superclusters have been prepared using a percolation algorithm applied to a complete sample of UGC galaxies brighter than the 14.5 magnitude. Both a two dimensinal (projected) and a three dimensional approach have been tried. The (conservative) result is that superclusters are certainly not spherical. Probably the departure from sphericity is towards elongated cigar-like structers. No evidence of relative alignements of superclusters has been found.
