History for finite simple groups
Classification
The full classification is generally accepted as starting with the Feit?Thompson theorem of 1962/63, largely lasting until 1983, but only being finished in 2004.
Soon after the construction of the Monster in 1981, a proof, totaling more than 10,000 pages, was supplied that group theorists had successfully listed all finite simple groups, with victory declared in 1983 by Daniel Gorenstein.
This was premature ? some gaps were later discovered, notably in the classification of quasithin groups, which were eventually replaced in 2004 by a 1,300 page classification of quasithin groups, which is now generally accepted as complete.
