  An open-access program allowing three-item statement matrices to be generated
from data such as molecular sequences does not exist so far. The recently
developed LisBeth package (ver. 1.0) allows representing hypotheses of homology
among taxa or areas directly as rooted trees or as hierarchies; however, this
is not a standard matrix-based platform. Here we present "TAXON version 1.1"
(TAXON), a program designed for building three-item statement-matrices from
binary, additive (ordered) and non-additive (unordered) multistate characters,
with both fractional and uniform weighting of the resulted statements.
