I am interested to know the largest computed summatory liouville interval, an implementation of which is detailed in Section 4.1 of [1].

The wikipedia page [2] for the function charts summatory liouville up to an interval of 10$^7$. I would like to know the largest computed summatory liouville value. Where might be the best reference to find this out?

Best,
