A question about # of walls

[FelipeXIX]

I've seen several sources that have 168 as the # of walls at the atomic age, but I only have 162. Any ideas on how to get these 6 missing walls?

According to the wiki (https://dominations.fandom.com/wiki/Wall), 162 at Atomic age.

Strangely enough, on that same website under the atomic age chapter, it has max walls as 168. Thanks for helping tho. I'll just call it a typo and rest easy.
