Definition
Glossary of "Cladistics (2nd ed.)" by Kitching et al. (1998)
- A three-item statement that is logically implied by the combination of two other three-item statements is redundant. For example, the statement A(BCD) yields the three-item statements: A(BC), A(BD) and A(CD). Combination of any two will recover the original statement, A(BCD), making the third redundant. Redundancy is accounted for by fractional weighting.
