Symmetric relations.
Signs of corresponding functions are different.
Function interaction: 1 ↔ 7, 2 ↔ 8, 3 ↔ 5, 4 ↔ 6.

Cross-interaction between the partners' ego and id blocks makes evident that both partners are competent in only two macro elements and are not competent in the other two macro elements. There is no full understanding of high dimensional functions because a vital superblock always "has its own opinions", i.e. obstinately  directed towards satisfying its own needs. Values and mental elements of one of the partners, stay out of the interest zone of the other. A similar situation is with the superego and superid blocks - superid values and interests of one of the partners do not interest and even irritate  his  partner.  However, at first encounter, information coming from the pertner's function 3 can be attractive, because of the tendency to show-off ones role function when meeting new people. In long-term relationships partners can feel lack of infromation feed to superid and can realize that they have different values while they still have enough understanding of their high-demensional blocks. Efficient cooperation of the high-dimensional blocks when working on some specific tasks is still posible.
