Details

This message is generated when the arguments in ClebschGordan, ThreeJSymbol, or SixJSymbol fail to satisfy the required triangle inequality.
Off[message] switches off the message; On[message] switches it on. For example: Off[ClebschGordan::tri].

Examples

An error occurs in this example because the indicated decomposition is not possible:

Wolfram Language code: ClebschGordan[{1, 0}, {2, 0}, {4, 0}]

This shows a physically valid Clebsch–Gordan coefficient:

Wolfram Language code: ClebschGordan[{1, 0}, {2, 0}, {3, 0}]

A similar error can also occur for ThreeJSymbol or SixJSymbol:

Wolfram Language code: SixJSymbol[{1, 1, 1}, {2, 5, 5}]
