In QPA2 one can compute all possibilities, one-sided with one-side, two-sided with one-sided, one-sided with two-sided and two-sided with two-sided, and get as an result a vector space, one-sided module or a two-sided module. QPA2 is available from the above link, but you also have to install the latest versions of the packages it depends on. Furthermore, can also compute different versions of Hom-spaces in QPA2, which were not available in QPA1. | |
