Let $G$ be an abelian group, and let $A$ be a finite subset of $G\setminus\{0\}$. An ordering $a_1,\ldots,a_{|A|}$ of $A$ is sequenceable if its partial sums … are pairwise distinc…

Let $p$ be a prime, and let $A\subseteq\mathbb{Z}_p\setminus\{0\}$. An ordering $a_1,\ldots,a_{|A|}$ of $A$ is valid if its partial sums … are pairwise distinct. Graham's conjectur…

Weak CMPP conjecture. If

CMPP conjecture. If

Weak sequenceability conjecture. The set $A$ is $t$-weak sequenceable. Equivalently, every abelian group is $t$-weak sequenceable.

Alspach–Liversidge conjecture. Every abelian group is strongly sequenceable.
