Most dense subset of numbers that avoids arbitrarily long arithmetic progressions
If you're interested in lower bounds for the largest set without a $k$AP, then Behrend's construction is still essentially the best known, and it gives a set of size $n\exp(c\sqrt{\log n})$ for some constant $c>0$. See this recent paper of Green and Wolf:
