The arguments with which libgap is started are set up in src/sage/libs/gap/util.pyx in the function initialize() - setting various members of argv. In particular look for what `-o` is set to. By digging through the code, it appears that it's set by set_gap_memory_pool_size() from interfaces/gap.py
So if you call set_gap_memory_pool_size with a big value, before starting libgap, you might get more (I didn't try) HTH, Dima On Tue, Sep 18, 2018 at 9:38 PM Simon Brandhorst <sbrandho...@web.de> wrote: > > sage: V = libgap.GF(13)^500 > sage: S = V.Subspaces(50) > sage: S.List() > gap: cannot extend the workspace any more! > > > As expected the computation runs out of memory.
