Tensor Calculations on Computer: Appendix In the main text of the paper [Comm. ACM 9, 12 (Dec. 196), 864], a FORMAC program was discussed which is capable of calculating various quantities of interest in tensor calculus. This Appendix is intended as an example of the program output. Chrisoffel symbols calculated for 12 basic orthogonal coordinate systems are listed. CACM March, 1967 Walton, J. J.
