A monoid M that admits a finite convergent presentation satisfies the
homological finiteness condition FPinfinity and Squier's combinatorial
property of having finite derivation type. Although Squier has given
an example of a finitely presented monoid S-1 that satisfies the condi
tion FPinfinity, but that does not have finite derivation type, the ex
act relationship between these two conditions is unsolved. Here we est
ablish a partial result by showing that for finitely presented monoids
the property of having finite derivation type implies the homological
finiteness conditions FP3. Hence, the property FP3 is strictly weaker
than the property of having finite derivation type.
