N = 5, giving a geometrical construction of the congruence of lines [B.sub.MA] in [P.sup.5] in this way obtained: it results to be a first order congruence and a smooth Fano 4-fold in [P.sup.11] in the Plucker embedding; its focal locus is a sextic threefold X such that the lines of [B.sub.MA] through a general point of X form a (planar) pencil.
