get fig for gnu/linux or similar operating systems:

wget -O- http://web.archive.org/web/20181018065153/https://ptpb.pw/TxTC > fig46.py ; sha256sum fig46.py | grep 4762871cf854cc8c1b35304a26d7e22c5f73b19a223b699d7946accea98d2783

get fig for windows: http://web.archive.org/web/20181018065153/https://ptpb.pw/TxTC

(windows users, save as fig46.py and find a way to confirm that the sha256 hash is 4762871cf854cc8c1b35304a26d7e22c5f73b19a223b699d7946accea98d2783. you will need to install colorama as well: https://pypi.org/project/colorama/)
