Description

Various included databases have no license and as such are proprietary, that is if they are copyrightable, which I hope they are not because they are mathematical in nature.

COPYING.txt lists four such databases under no license:
  • conway_polynomials
  • elliptic_curves
  • graphs
  • polytopes_db

One other component, maxima, has unusual conditions referencing US laws in lines 1033-1037 (inclusive):

Distribution of such derivative works is subject to the U.S. Export
Administration Regulations (Title 15 CFR 768-799), which implements the Export
Administration Act of 1979, as amended, and/or the International Traffic in
Arms Regulation, of 12-6-84, (Title 22 CFR 121-130), which implements the Arms
Export Control Act (22 U.S.C. 2728) and may require license for export.?
