In the Acknowledgements in the 1975 edition of The Invisible Landscape we read:
... we wish to especially thank Leon Taylor and Royce Kelley, both of whom were tireless in their dedication to the computer programming involved in the extrapolation and displaying of the I Ching graph. The material in the appendices is their work, as are illustrations 17-27.
One of the appendices contains a table of 384 lines, later known as the "Table of Intermediate and Final Values".
