The plane spanned by the tangent vector T and binormal vector B.

A mathematical relationship expressing f_n as some combination of f_i with i<n. When formulated as an equation to be solved, recurrence relations are known as recurrence ...

A set A of integers is recursively isomorphic to set B if there is a bijective recursive function f such that f(A)=B.

The coloring red of two complete subgraphs of n/2 points (for even n) in order to generate a blue-empty graph.

The Reeb foliation of the hypersphere S^3 is a foliation constructed as the union of two solid tori with common boundary.

A type of error-correcting code that is related to Hadamard matrices.

A reflex angle is an angle of more than 180 degrees. A full angle is therefore a reflex angle, while acute, obtuse, right, and straight angles are not.

An object is reflexible if it is superposable with its image in a plane mirror. Also called amphichiral.
