Definition: In mathematics, "supercanonical" refers to a specific type of configuration space in geometric topology. Supercanonically defined spaces are those for which all but one point is non-orientable. The concept of supercanonically defined spaces was introduced by John Nash and others in the 1970s. It involves a topological space X with a collection of subspaces, called the canonical subspaces, that define its fundamental group π_1(X). These subspaces are required
