The numbered entries below all describe the SAME block (concept) for the topic "{topic}", just worded differently. Pick the ONE entry whose title is the best canonical name for this block — and optionally propose a SHORTER canonical name if none of the titles states the shared core precisely.

MEMBERS:
{members}

Rules:
- "best" is REQUIRED: the member whose title fits the shared concept best (most concrete, precise, self-explanatory, established term; avoid reference/placeholder titles like "Satz 7.18", "Punkt 3", "(**)").
- "name" is OPTIONAL — set it ONLY when no member title states the shared core well. It must be SHORT (max 8 words), use ONLY terms that appear in the members themselves, and stay exactly as concrete as the shared content — never a broader umbrella term, never a textbook concept the members don't mention.
- In "name": NO catalog/reference brackets ("(Satz 6.33)", "(Kap. 4)"); a known acronym in brackets ("(VC)") is fine.
- The title is the CONCEPT name — a source numbering is never canonical. Even with a name attached ("Satz 7.13 (Christofides)", "Satz 7.6: Kriterium für Eulerschen Kreis"), pick or propose the concept/result ("Satz von Christofides", "Kriterium für Eulerschen Kreis"); the numbering belongs in the description, never in the title.

Reply with ONLY the JSON — no code fences, no other text.
