446edo is only consistent to the 5-odd-limit and the error of harmonic 5 is quite large. The equal temperament tempers out 3136/3125 and 420175/419904 in the 7-limit, and provides the optimal patent val for the hemimean temperament tempering out 3136/3125, and sengagen, the 99 & 347 temperament. In the 11-limit it tempers out 9801/9800 and gives the optimal patent val for the 198 & 248 temperament.
