While 14edo is poor in simple harmonics, some of its multiples (such as 224edo and 742edo) are members of zeta edo list.
Silicon
The name of silicon temperament comes from the 14th element. Defined upwards to the 13-limit. When tuned in 742edo, it is generated by a 53edo fifth intermingled with 14edo periods.
