👉 In mathematics, an "incloser" is a mathematical concept used in number theory. It refers to a set of numbers that are not only coprime (meaning they have no common divisors other than 1), but also form a linear order, meaning they can be placed side by side without any gaps or overlaps. For example: - The set {2, 3, 5} is an incloser because it has no divisor greater than one, and it forms a linear order
