So I heard that graham's number for example was considered the largest named number in 1975, but I also read that there were other larger numbers then (like graham's number with 4's instead of 3's) as well as functions like the ackermann function. My question is, did mathematicians use large numbers like that before then? or did graham just come up with the idea to iterate up arrows on the spot? it's not that hard of a concept (iterating hyperoperations) so did mathematicians or just regular people use numbers larger than g64 before? what about numbers like tree(3)?
