[racket-users] nj-symbols
To whom may be interested, Repository https://github.com/joskoot/nj-symbols Provides procedures for the exact computation of the squares of 3j-, 6j- and 9j-symbols. For documentation a scribble module is included. Jos -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

[racket-users] nj-symbols and clebsch-gordon coefficients
Hi IIRC all nj-symbols and Clebsch-Gordon coefficients are plus or minus the square root of a positive rational number. IIAC this means that a nj-symbol or Clebsch-Gordon coefficient can be represented exactly by a sign and its square. Question: is this correct? If so, is there already some code that does this. If not, I am prepared to produce it (using a hash in order to speed up) The recursion relations seem to confirm my IIRC of the first line. Would this be usefull?
