3: 34.10 Zeros
In a 3 j symbol, if the three angular momenta j 1 , j 2 , j 3 do not satisfy the triangle conditions (34.2.1), or if the projective quantum numbers do not satisfy (34.2.3), then the 3 j symbol is zero. Similarly the 6 j symbol (34.4.1) vanishes when the triangle conditions are not satisfied by any of the four 3 j symbols in the summation. …However, the 3 j and 6 j symbols may vanish for certain combinations of the angular momenta and projective quantum numbers even when the triangle conditions are fulfilled. …

6: 3.2 Linear Algebra
§3.2(iii) Condition of Linear Systems
The sensitivity of the solution vector x in (3.2.1) to small perturbations in the matrix A and the vector b is measured by the condition number …The larger the value κ ( A ) , the more ill-conditioned the system. …
§3.2(v) Condition of Eigenvalues
If A is nondefective and λ is a simple zero of p n ( λ ) , then the sensitivity of λ to small perturbations in the matrix A is measured by the condition number
