\section{Summary}

We have presented the three main ingredients to compute three- and four-electron integrals involving GGs.
|
|
Firstly, a straightforward method to compute the FIs is given.
|
|
Secondly, our UBs strategy is briefly discussed.
|
|
Finally, the significant integrals are computed via a recursive scheme based on vertical and horizontal RRs, which can be viewed as an extension of the PRISM late-contraction path to three- and four-electron integrals.
|
|
We believe our approach represents a major step towards an accurate and efficient computational scheme for three- and four-electron integrals.
|
|
It also paves the way to contraction-effective methods for these types of integrals.
|
|
In particular, an early-contraction scheme (including the contraction of both basis functions and Gaussian geminals) would have significant computational benefits.
