Theory
339et is only consistent to the 5-odd-limit. It can be used for the 2.3.5.13.19.23.31.41 subgroup, tempering out 780/779, 621/620, 1426/1425, 1026/1025, 2945/2944, 14391/14375 and 73853/73800. Using the 339d val (⟨339 537 787 951]) in the 7-limit and the 339de val (⟨339 537 787 951 1172]) in the 11-limit, it supports tritriple.

Subsets and supersets
339 factors into 3 × 113, with 3edo and 113edo as its subset edos. 1017edo, which triples it, gives a good correction to the harmonics 7 and 11.
