WebJan 2, 2024 · Finally I found out that the problem was not in the ERIs but on the way I was using the 8-fold permutational symmetry of the ERIs to do only the unique integrals. I constructed the ERI(a,b,c,d) matrix using this symmetry, and when I switched back to doing the full matrix, there were about 4 elements (in 17^4) that had some deviations.
