Methods of computation for $\mathit{3}\beta \x81\u2019j$ and $\mathit{6}\beta \x81\u2019j$ symbols include recursion relations, see Schulten and Gordon (1975a), Luscombe and Luban (1998), and Edmonds (1974, pp. 42β45, 48β51, 97β99); summation of single-sum expressions for these symbols, see Varshalovich et al. (1988, Β§Β§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 $\mathit{9}\beta \x81\u2019j$ 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, Β§10.2.1) and Srinivasa Rao et al. (1989). A review of methods of computation is given in Srinivasa Rao and Rajeswari (1993, ChapterΒ VII, pp. 235β265).
