About
This collaborative project
is a database of combinatorial collections, maps and statistics:
- a combinatorial collection is a collection $\mathcal{S} = \bigcup_{i}\mathcal{S}_i$ of finite sets $\mathcal{S}_i$,
- a combinatorial map is a map $\phi: \mathcal{S} \longrightarrow \mathcal{S'}$ between two combinatorial collections,
- a combinatorial statistic is a map $\operatorname{st}: \mathcal{S} \longrightarrow \mathbb{Z}$.
is a search engine, identifying your data as the composition of known maps and statistics.
