Number Theory
Jevons had written in his Principles of Science, p. 123, "Can the reader say what two numbers multiplied together will produce the number 8616460799 ? I think it unlikely that anyone but myself will ever know." This became known as Jevons' Number and was factored by Derrick Norman Lehmer in 1903 and later on a pocket calculator by Solomon W. Golomb.

And long enough gets rated as a creed....”
