Abstract
Results giving the exact crossing number of an infinite family of graphs on some surface are very scarce. In this paper we show the following: for G = Q~n~ × K~4.4~, cr~y(G)‐m~(G) = 4__m__, for 0 ⩽ = m ⩽ 2^n^. A generalization is obtained, for certain repeated cartesian products of bipartite graphs. Nonorientable analogs are also developed.

## Abstract Zip product was recently used in a note establishing the crossing number of the Cartesian product __K__~1~,__n__ □ __P__~m~. In this article, we further investigate the relations of this graph operation with the crossing numbers of graphs. First, we use a refining of the embedding metho
## Abstract Crossing numbers of Sierpiński graphs __S__(__n__,__k__) and their regularizations __S__^+^(__n__,__k__) and __S__^++^(__n__,__k__) are studied. Drawings of these graphs are presented and proved to be optimal for __S__^+^(__n__,__k__) and __S__^++^(__n__,__k__) for every __n__ ≥ 1 and _
