By brute force on F_3^2 and F_3^3 (9 and 27 points respectively, small enough to check by hand or trivial script), determine exactly which small point sets are cap sets, and use this to double check the equivalence between 'no three distinct points sum to 0 mod 3' and 'no 3-term arithmetic progression'. Post the findings so others do not have to re-derive this.
