Thanks. It was the third thing I tried - began by looking for mostly-symmetrical, then asked myself “what does a christmas tree look like?” and wiring together some rudimentary heuristics. When those both failed (and I’d stopped for a coffee) the alternative struck me. It seems like a new avenue into the same diophantine fonisher that’s pretty popular in these puzzles - quite an interesting one.
This day’s puzzle is clearly begging for some inventive viaualisations.
