Jupyter notebook works with wolfram engine 13 on ubuntu (gwls2 and
ubuntu22.04 i am using), but maybe it shouldn't be difficult to adapt it ?
I am not good enaugh for this but I think we are on a near way ?

something in their output format... Since I know zilch about HTML
mysteries and miseries, I can't offer anything but my warmest
condolences...
By the way, has anyone tried https://www.wolfram.com/engine/ ?
We can think of making an interface to it, as it's a free and locally
installable.
[ Sorry for the late answer : I moved (only a couple miles, bit that's
still a quarter of a century of life...), and I managed to dig up my
computer from the resulting mess only this morning... :-) ]
Yes, yes, yes : easy comparison to Wolfram's (Mathematica's) result
may be important in various contexts (and may offer a solution where
none of Sage's tools works, e. g. various primitive search problems).
A "nice" presentation could be, like our current Mathematica
interface, a standard package compilable without Wolfram Engine
having to be present on the target machine, giving an informative
error message if called on a machine without the engine, but giving
back the expected result if present.
The documentation should include (a pointer to) instructions on how to
install the Wolfram engine.
That could revive my log of untranslatable Mathematica results, for
which I have some proposals (but didn't bother to formally file, since
enhancing access to a non-free product may not be a priority...). If
something gratis, not (too much) encumbered and not-too-hard to
install can be obtained without too much hassle, that should become
a priority.
