The question of the possibility of formation of neutron matter, which is a Bose condensate of dineutrons, is discussed. It is believed that the existence of stable dineutrons is confirmed by the presence of a neutron anomaly in ultracold neutron (UCN) gas. It is shown that the time of dineutron formation in UCN gas in this case is approximately 27 hours. A scheme for creating a storage trap for dineutrons has been proposed. A conclusion is made about the possibility of formation of a Bose condensate of UCN gas at an arbitrarily small concentration of neutrons in the trap at a temperature T below the critical temperature Tc of the neutron Bose condensate T_c = 10^-3. It is shown that the maximum density of neutron matter in the Bose condensate is four orders of magnitude higher than the density of ordinary matter.
