  In any metrical tree or constituent, the HTE of the subconstituent dominated by l is: a. One register step lower than the HTE of the subconstituent dominated by h when the l subconstituent is on the right; b. at the same register as the HTE of the subconstituent dominated by h when the l subconstituent is on the left.

- 2008, Terwilliger Algebras of Wreath Products of Association Schemes, →ISBN:
  During 1992 and 1993 Paul Terwilliger introduced a new tool called the subconstituent algebra for studying the underlying structure of association schemes through a series of three papers [21], [22], and [23]. Terwilliger introduced a method for studying commutative association schemes by defining a new algebra that is noncommutative, finite dimensional, semisimple C-algebra. The subconstituent algebra is now popularly referred to as the "Terwilliger" algebra.
(physics) A component of an elementary particle.
