Actually my bad, there are 3 valid extensions to microorganismic so here they are

It splits the septischisma in 3 parts and the pythrabian comma in 5 parts, each of these parts being a tempered [[olympia]]~[[argyria]].
It splits the septischisma in 3 parts and the pythrabian comma in 5 parts, each of these parts being a tempered [[olympia]]~[[argyria]]. It has three valid 13-limit extensions, each of them basically just as accurate, but only koch is a strong extension.
