Decomposition of ambient Lie algebra: Vω2+2ω3+ω4⊕Vω1+2ω3+ω4⊕V4ω3⊕Vω2+2ω3⊕Vω1+2ω3⊕V2ω4⊕V2ω3⊕Vω1+ω2⊕2Vω4⊕V0
Primal decomposition of the ambient Lie algebra. This decomposition refines the above decomposition (please note the order is not the same as above). Vω4+6ψ⊕Vω1+2ω3+4ψ⊕Vω2+2ω3+ω4+2ψ⊕V4ω3⊕V2ω4⊕V2ω3⊕Vω1+ω2⊕Vω1+2ω3+ω4−2ψ⊕V0⊕Vω2+2ω3−4ψ⊕Vω4−6ψ
In the table below we indicate the highest weight vectors of the decomposition of the ambient Lie algebra as a module over the semisimple part. The second row indicates weights of the highest weight vectors relative to the Cartan of the semisimple subalgebra. As the centralizer is well-chosen and the centralizer of our subalgebra is non-trivial, we may in addition split highest weight vectors with the same weight over the semisimple part over the centralizer (recall that the centralizer preserves the weights over the subalgebra and in particular acts on the highest weight vectors). Therefore we have chosen our highest weight vectors to be, in addition, weight vectors over the Cartan of the centralizer of the starting subalgebra. Their weight over the sum of the Cartans of the semisimple subalgebra and its centralizer is indicated in the third row. The weights corresponding to the Cartan of the centralizer are again indicated with the letter \omega. As there is no preferred way of chosing a basis of the Cartan of the centralizer (unlike the starting semisimple Lie algebra: there we have a preferred basis induced by the fundamental weights), our centralizer weights are simply given by the constant by which the k^th basis element of the Cartan of the centralizer acts on the highest weight vector. Here, we use the choice for basis of the Cartan of the centralizer given at the start of the page.

Highest vectors of representations (total 11) ; the vectors are over the primal subalgebra.−h3+h1g3g1g35g6+g5g7g33g21g11g34g24
