Hi!
Have you tried the StatisticsCalculator transformer?
Group By: Name
Attributes to Analyze: Surface
You could also sort by surface in reverse order then use a duplicatefilter filtering on name to keep only the polygon with the largest surface for each name
Thank you egomm
how do i filter 250 names?

Sort by Area descending and name.
Then use a Sampler, 1, first N features.
Thank you. The answer from Gio works perfectly.
