Or, largest size of an ndimensional capset (i.e., a subset of (Z/3Z)^n that does not contain any lines {a, a+r, a+2r}).  Terence Tao, Feb 20 2009
Or, size of maximal cap in the affine geometry AG(n+1,3).  N. J. A. Sloane, Oct 25 2014
It may only be a conjecture that the interpretation in terms of the SET game gives the same sequence for all n as the maximal cap problem.  N. J. A. Sloane, Oct 25 2014, following a conversation with James Abello.
