AB - Let $Y \subset l^n_\infty $ be a subspace of codimension two. For $n = 4$ the formula for cominimal projections will be presented. For $n = 5$ the complete characterization of $I$-sets which determined cominimal projections and consequently the manner of finding cominimal projections will be given. This completes the results from [15].
