Abstract

A well-known result of Tutte is that U2,4, the 4-point line, is the only non-binary matroid M such that, for every element e, both Mβe and M e, the deletion and contraction of e from M, are binary. This paper characterizes those non-binary matroids M such that, for every element e, Mβe or M e is binary. © 1990.
