Methods of computation for 
and 
symbols include recursion relations,
see Schulten and Gordon (1975a), Luscombe and Luban (1998), and
Edmonds (1974, pp. 42–45, 48–51, 97–99); summation of single-sum
expressions for these symbols, see
Varshalovich et al. (1988, §§8.2.6, 9.2.1) and Fang and Shriner (1992);
evaluation of the generalized hypergeometric functions of unit argument that
represent these symbols, see Srinivasa Rao and Venkatesh (1978) and
Srinivasa Rao (1981).
For 
symbols, methods include evaluation of the single-sum series
(34.6.2), see Fang and Shriner (1992); evaluation of triple-sum
series, see Varshalovich et al. (1988, §10.2.1) and
Srinivasa Rao et al. (1989). A review of methods of computation is given in
Srinivasa Rao and Rajeswari (1993, Chapter VII, pp. 235–265). See also
Roothaan and Lai (1997) and references given there.
