Amendments to Re67
I still didn't say it clearly enough: A sequence is an ordered list of elements; a series is a sum of a sequence. Both can be either finite or infinite.^1
And see Retraice (2022/12/01) for more clear notes on how the last term in our table sequence is an exponential function.
Warnings about Python
Python is a modern, fast-evolving language and ecosystem. This means you might write code that works today, but won't work next year because underlying dependencies have changed. Use pyenv to control your Python version, and use venv (Python built-in) or pipenv or virtualenv to control your Python packages. (Docker is beyond the scope of this segment.)
* https://github.com/pyenv/pyenv
* https://docs.python.org/3/library/venv.html
* https://pipenv.pypa.io/en/latest/ (alternative to venv)
* https://virtualenv.pypa.io/en/latest/ (alternative to venv)
* https://en.wikipedia.org/wiki/Docker_(software) (a more production-oriented, general solution)
Using Python to do the sum
We're focusing on the math and code of AIMA4e.^2 Today we write Python code to do the arithmetic of our mathematical series that tells us how many entries in a look-up table are required for a TABLE-DRIVEN-AGENT, depending on the number of things it can perceive, and how many moments of perception it will have. The table gets big very, very quickly.

The algebra and arithmetic (see Retraice (2022/12/01)), and a Python for-loop for calculating the number of entries needed in our lookup table. The code is at: https://github.com/retraice/ReAIMA4e
