Abstract:
For Box-quasimetric of the canonical Engel group considered as symmetric $(q_1,q_2)$ quasimetric, the description of the domain of its admissible parameters $q_1,q_2$ is obtained. The minimum value of the constant $q$ in its $(q,q)$-generalized triangle inequality is found implicitly.
Key words:$(q_1,q_2)$-quasimetric, Box-quasimetric, canonical Engel group, admissible parameters.
