This application accesses a database of minimal zero-sum sequences with terms in the range \([-18,18]\) and their derived relationships.


Query parents (derived from) or children (derivations) of a given sequence.

The sequence \(6^2 \cdot (-4)^2 \cdot (-3)^1 \cdot (-1)^1\) is encoded as "-1 0 -1 -2 0 2".

If you give it a non minimal sequence, nothing will be generated.

Maximal Sequences

Query maximal elements for a given value of \(k, [-k, k]\)

\(t\) Distinct Terms

Query sequences from \(k, [-k, k]\) with \(t\) distinct terms
