Description: The dimension theorem for vector spaces: any two bases of the same vector space are equinumerous. Proven by using lssacsex 20181 and lbsacsbs 20193 to show that being a basis for a vector space is equivalent to being a basis for the associated algebraic closure system, and then using acsexdimd 18065.
