I'm trying to find the correct nomenclature for a cyclohexane with four substituents. The stereochemistry of the cyclohexane is (1R, 2R, 5S, 6S). The methyl groups on 1 and 6 are pointed away and the groups on 2 and 5 are pointed towards you.

I know 2 substituents is di- and 3 substituents is tri- but what's four?

THANK YOU!!

Four? Tetra...

I'm not sure how you'd call the stereochemistry.
