English
The embedding of m2 from M2 into the product Clifford algebra corresponds to the right component embedding, i.e., toProd Q1 Q2 (1 ⊗ ι Q2 m2) = ι (prod) (0, m2).
Русский
Встраивание в произведение Clifford-алгебры элемента из M2 соответствует правому компоненту: toProd Q1 Q2 (1 ⊗ ι Q2 m2) = ι (prod) (0, m2).
