I don't think your problem was the spec of your pc, although 8GB is
pretty good.
Mine, with 16GB RAM, got stuck with taking all triples, seeming to need
~38GB,
and Raul's analysis also suggests 40GB .

Please note, first, that your output might not be quite right,
as, for example. the triple 8 9 10 evaluates as 990. There

I expect the answer depends on your setup, but, at least in mine, in
JQt under Windows 10, I have
the line numbers option set to ON. The sequence ALT-v-n toggles that
option, ie VIEW/Toggle Line Numbers
If it's still difficult to spot what's going wrong, you can try
reloading your

You are given $S(3) \approx 14.6461$ and $S(5) \approx 124.1056$.
Find $S(25)$, rounded to 4 decimal places.

Try deleting your J installation and install again.
