506edo is a strong 5-limit system, correcting 253edo's mapping for 5. It tunes a number of strong 5-limit temperaments like vishnu, monzismic, and lafa. It also tunes stockhausenic and geb temperaments. The 506e val tempers out the swetisma and tunes hades.
506edo tempers out the major arcana comma, tempering out which divides the octave in 22 parts, and it is the only patent val supporting the 7-limit extension of this temperament, though 506edo's 7th harmonic is with a large error. It also tunes the palladium temperament in the 5-limit.
