1612edo is a strong 5-limit system, but it is only consistent to the 5-odd-limit since harmonics 7 and 11 are about halfway between its steps. Nonetheless, the patent val is a strong 2.3.5.13.17.23.29.31 subgroup tuning.
It provides a tuning for quasithird, aluminium and counterorson temperaments in the 5-limit.

Since 1612 factors into 22 × 13 × 31, 1612edo has subset edos 2, 4, 13, 26, 31, 52, 62, 124, 403, and 806. 3224edo, which doubles 1612edo, corrects the mapping for 7 and 11.
