Soft set theory is a useful mathematical tool to deal with uncertainty in a parametric manner. Near sets have been used as a tool to study extensions of topological spaces. The present paper introduces and studies nearness of finite order, ππππ β merotopy, in soft set theory. An ππππ β merotopic space (ππ, ππππ ,πΈπΈ) is introduced for a given ππππ β merotopic space (ππ, ππ, πΈπΈ), where ππ and ππ are integers with the restriction that 2 β€ ππ β€ ππ. For ππ β€ ππ an ππππ β merotopy ππβ from a given ππππ β merotopy ππ having the property that ππ = (ππβ)ππ is constructed and the largest ππππ β merotopy having such property is derived. For an ππππ β merotopic space (ππ, ππ), every maximal ππ β compatible family is a maximal ππ β clan.
