It is shown that, for a one-centre universal even-tempered basis set containing N functions, only N of the N(N + 1)/2 eigenvalues of the two-electron integral matrix are larger than some small ΓΆ as N becomes large and thus only N of the rows or columns of the matrix are linearly independent in this
