Abstract
Weak nonleptonic amplitudes are discussed in the scheme on the assumption of octet dominance. The contributions to hyperon-decay waves of spurions of representations higher than 143 of the current ⊗ current product are discussed in detail. In addition to Gell-Mann's relations for hyperon waves we find that is forbidden in waves apart from minor kinematical corrections. Possible modifications from a kinetic-energy spurion are also examined. Some remarks concerning consequences of invariance and concerning decays are included.
