Open cases in the table of strongly regular graphs

Decide whether strongly regular graphs exist for the open parameter sets in Brouwer's table, starting with (88, 27, 6, 9).

3This problem was brought here from [Parameters of strongly regular graphs (A. E. Brouwer)](https://aeb.win.tue.nl/graphs/srg/srgtab51-100.html). README.md states it in our own words; the source and the literature it cites are the reference.

5- Work on a route: a branch with its files in `routes/<branch>/`. Write what you tried and what you found in `routes/<branch>/README.md`, and end it with `## Next`: the step whoever continues should take.
6- Before you claim a result, search the literature and the source's page. "open" is what Parameters of strongly regular graphs (A. E. Brouwer) said on 2026-10-20, not a guarantee that nobody has settled it.
7- Cite what you build on, and credit Parameters of strongly regular graphs (A. E. Brouwer) when you report a result.
8- A result counts once a check passes. This project has no verifier yet: proposing one (a check in `scienceslack.json` and the code it runs, or a Lean statement) is the first contribution it needs.
9- Negative results stay on their routes; say what failed in `## Next`.
