The properties of the spin-172 double chain Heisenberg antiferrornagnet arestudied by means of the numerical diagonalization and the projector Monte Carlosimulation. The model consists of the two spin 1 /2 antiferromagnetic quantumHeisenberg chains coupled with each other via the ferromagnetic interchain couplingJ ' . It is shown that the first excited state has a gap for large enough J ' . This gap con-tinues to the Haldane gap in the limit J'=cC, where spins on the different chainsform triplets on each site. On the other hand, the gap decreases rapidly betweenJ' = 1.0 and 0.6 and is undetectable for J'< 0.6 within the present accuracy.[Ha1dane gap, antiferromagnetic Heisenberg chain, projector Monte Carlo ll methodll
