How to call GAPs SmallGroup from sage? (I am getting an error, though the correct library is installed.)
I am trying to call GAP's SmallGroup program from within SAGE.
When I run gap_console(); from Sage I have the banner that indicates the SmallGroup library is present:
Components: small 2.1, small2 2.0, small3 2.0, small4 1.0, small5 1.0, small6 1.0, small7 1.0, small8 1.0, small9 1.0, small10 0.2, id2 3.0, id3 2.1, id4 1.0, id5 1.0, id6 1.0, id9 1.0, id10 0.1, prim 2.1 loaded. Packages: CTblLib 1.1.3 loaded.
Moreover, I can use SmallGroup from within this session of GAP run in SAGE.
The problem is that when I try to run SmallGroup from within SAGE (via gap.SmallGroup(12,3) for instance)
I get the error copied below, which suggests that SmallGroups is not installed in GAP (even though it is):
What can I do?
I loaded the version of GAP that I downloaded seperately instead of the one that came with SAGE via the commands:
import sage.interfaces.gap sage.interfaces.gap.gap_cmd = "/usr/bin/gap -r"
Thank you very much!
