Another good link concerned with this problem is from OEIS:

"Maximum numbers of cards that would have no SET in an n-attribute version of the SET card game"

The OEIS links appear to have been updated to reflect the recent breakthrough of Ellenberg and Gijswijt, including their unified paper arXiv:1605.09223 from May 30.
