We introduce a simple algorithm providing a compressed representation () of an irreducible Hamiltonian matrix (number of magnons constrained, dimension: ) of the spin-1/2 Heisenberg antiferromagnet on the non-periodic lattice, not looking for a good basis. As increases, the ratio of the matrix dimension to converges to 8 (order of the symmetry group of square) for the exact ground state computation. The sparsity of the Hamiltonian is retained in the compressed representation. Thus, the computational time and memory consumptions are reduced in proportion to the ratio.
