"There're many books introducing rubik's cube and its solution, the number of books of this kind published each year was counted by Georges Helm as below: 14 in 1979, 52 in 1980, 174 in 1981, 70 in 1982, 15 in 1983."
By the way, would you please tell me the name of the book that the words are quoted from?
