If I wanted to write puts at a strike of 80, but the options series doesn't go below 100, is there a way to synthesize this position?

Depending on how big a trade you wanted to put up you could request the strike be added. Obviously they're not going to add it for a small retail trade. Both the PHLX and CBOE also offer FLEX options with custom date and strikes, but I dont recall off the top of my head what the minimum size is.
