What is recorded here?
Replaced the lengths and shapes of a bridge layout with its connection pattern and a parity argument, ruling out a walk that crosses each of the seven bridges exactly once.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
The publication year follows the Euler Archive, which separately records 1735 as the written date. This record credits the bridge argument, not every modern graph theorem or a complete modern proof of the sufficient Euler-trail criterion.
