COMMENT

Although Joyce mentions (9^9)^9, he clearly intended to refer to 9^(9^9).

(9^9)^9 is only 196627050475552913618075908526912116283103450944214766927315415537966391196809, whereas 9^(9^9) has 369693100 digits.

REFERENCES

C. A. Laisant (1906) proved that the number of digits of a(9), 9^9^9, is 369693100. H. S. Uhler (1947) published the log of the number to 250 decimal places.

EXAMPLE

"Because some years previously in 1886 when occupied with the problem

of the quadrature of the circle he had learned of the existence of a

number computed to a relative degree of accuracy to be of such

magnitude and of so many places, e.g. the 9th power of the 9th power

of 9, that, the result having been obtained, 33 closely printed volumes

of 1000 pages each of innumerable quires and reams of India paper would

have to be requisitioned in order to contain the complete tale of its

printed integers of units, tens, hundreds, thousands, tens of

thousands, hundreds of thousands, millions, tens of millions, hundreds

of millions, billions, the nucleus of the nebula of every digit of

every series containing succinctly the potentiality of being raised

to the utmost kinetic elaboration of any power of any of its powers".
