N2c6

Could you clarify the intended context for N2c6? The term does not have a widely established, singular meaning, and I want to ensure the article is accurate. For example, is N2c6:

- a chemical formula or designation in chemistry (e.g., a compound with two nitrogen and six carbon atoms or a code used in a reaction scheme),

- a term in chess notation or a move description,

- a project, standard, dataset, or software version code,

- or something else entirely?

If you provide the domain or preferred interpretation, I can generate a concise, neutral wiki-style article (under 300 words). If no context is available, I can draft a disambiguation-style stub that outlines plausible interpretations and notes the ambiguity.
