Plain-language statement

For a finite group of odd order and a three-term-progression-free set ss, the normalized inner product between μsμs\mu_s*\mu_s and the uniform measure on 2s2s is exactly s2|s|^{-2}. The identity records the precise normalized count forced by the absence of nontrivial three-term progressions.
