This is a table of Clebsch-Gordan coefficients for SO(3) and a PARI/GP script to calculate them.
An equivalent and more comprehensive Java program is in arXiv:0908.3030
A Python program is in arXiv:1102.5125
To obtain PARI/GP use the Linux package manager, for example
zypper install pari-gp # openSUSE
sudo apt install pari-gp # Ubuntu
The ASCII table of the Clebsch-Gordan coefficients is then generated with
gp -q < CGord.gp
To increase or decrease the extend of the j1 maximum quantum
number in the output, edit the last line of CGord.gp
and change the 9/2 to some other positive half-integer value.
Because PARI/GP does not have an interface to generic command line
arguments, this editing is apparently the only way to
change that value.
The ASCII table of the 6j-Symbols is generated with
gp -q < 6j.gp
To increase or decrease the extend of the j1 maximum quantum
number in the output, edit the last line of 6j.gp
and change the 11/2 to some other positive half-integer value.
