I don't think so, but I didn't count the arrows. Is it G<100>? Big, but I think it doesn't approach Tree(5). See Numberphile -- Tree(G64) for a really fun and technical explanation of where they fall in the infinity system.
This does not count SCG(13), Loader's number, Rayo's number, (Big)Foot's number ... or Busy Beaver.
