Raymond Queneau’s Cent mille milliards de poèmes, published in 1961 is a set of ten sonnets printed on card with each line on a separated strip. As all ten sonnets have not just the same rhyme scheme but the same rhyme sounds, any lines from a sonnet can be combined with any from the nine others, so that there are 1014 (100,000,000,000,000) different poems. It would take some 200,000,000 years to read them all, even reading twenty-four hours a day. (Apologies for borrowing from Wikipedia.
