2Authored explanation

Example 2.5 constructs the minimal sum \((\alpha+\cdots+\alpha^{p-1})(\beta+\cdots+\beta^{q-1})+\gamma+\cdots+\gamma^{\ell-1}=0\) for three distinct primes. With \((p,q,\ell)=(3,5,7)\), its support has \((3-1)(5-1)+(7-1)=14\) distinct 105th roots. Lower Bound Theorem 4.8 gives 14 as the minimum support of an asymmetric minimal sum in this case. Uniqueness Theorem 6.5 says every asymmetric minimal element at that support or weight is similar to \(\sigma(P_1^*)\sigma(P_2^*)+\sigma(P_3^*)\). The paper defines similarity as rotation. This supplies a source-backed uniqueness result at weight 14. In exponent notation, the construction has support \(\{7,14,15,28,30,45,49,56,60,75,77,90,91,98\}\); translation by 15 gives this packet's canonical representative.
