An explicit representation is suggested for orthogonal generalized spherical harmonics with cubic-crystal and triclinic-sample symmetries. The representation employs sums and differences of orthogonal generalized spherical harmonics with cubic-crystal symmetry, previously described by Bunge fororthorhombic (or higher) sample symmetry, and is illustrated, forT : .ι μ ν, ι = 4 , 9, μ = 1 , ν = 1 to 5. This representation facilitates crystallite orientation distribution (COD)analysis (aka ODF analysis) for thesesymmetries, using the Bunge formalism.
