Abstract
Sufficient combinatorial conditions for weak and strong validity of randomization are well known for some common classes of designs with single error strata. These conditions are generalized to orthogonal designs with multiple error strata given by an association scheme on the plots and with a treatment decomposition also defined by an association scheme.
