AbstractWe study the B(6) and B(4)-T(4) small cancellation groups.
These classes include the usual C’(1/6) and C’(1/4)-T(4) metric small
cancellation groups. We show that every finitely presented B(4)-T(4)
or word-hyperbolic B(6) group acts properly discontinuously and cocompactly
on a CAT(0) cube complex. We show that finitely generated infinite
B(6) and B(4)-T(4) groups have codimension 1 subgroups and thus do not
have property (T). We show that a finitely presented B(6) group is wordhyperbolic
if and only if it contains no
$$ \mathbb{Z} \times \mathbb{Z} $$ subgroup.
