the latest version is called).
DrRacket tends to become unresponsive after it's been running for about an hour

Spooky. 2 weeks ago I saw a reference to this while reading the macros chapter
in SAtoP and was looking for a copy online.

If you already have a full time job in another industry, think very carefully
about what you are wishing for.

I think this is an overly narrow perspective.

Forget about the term generative recursion for a second.
I've coined a phrase that for me encapsulates much of the approach of the
Design Recipe - I call it Delta Programming.
Why - well you have a result you would like, you have your input and you have
in your template a bunch of expressions
I tried to get you to approach this as though nobody had told you about
generative recursion.
In which case you would/should have tried the tried and tested formula you
know, which should have led you to
(tabulate-div 20) and the simple recursion that follows is (tabulate-div 19).
You have
An alternative approach.
1. Write a program called tabulate-20 that returns all the factors of 20
starting from 1.
2. Abstract tabulate-20 so that it works for numbers other than 20.
