This code is very experimental and could have subtle mistakes. Use with caution.

Often, trapezoidal quadrature is already superior to Gregory (and repeated Simpson) for small k, but very high order Gregory quadrature can beat it.

Enjoy!!

It seems to be the same method as Appendix I and II of
https://doi.org/10.1093/imanum/2.2.131
This paper is a very good reference.
