The Open Science Collaboration's reproducibility study had 270 coauthors.
Notes on verification
Confirmed by the official Center for Open Science press release, the published paper's own text, and a bibliographic database. One outlier secondary source (FiveThirtyEight) cites a different number but is inconsistent with primary/official sources.
