I am looking for a word or phrase like "pangram" that signifies an example of something that contains all the allowable contents of that class of object:
- "1,234.567809" contains all the generally-allowed symbols for a (US) number
- "1 + 2 × (3 / 4)" contains all the basic arithmetic operations
- Or an example sentence without the concrete example: "this program is a Python 'pangram': it contains usages of every allowable syntax of the language."
It seems to me that "pangram" itself might fit the bill, but this usage would stretch the definitions a bit:
pangram, n. (OED)
A sentence containing every letter of the alphabet.
pangram, n. (M-W)
a short sentence containing all 26 letters of the English alphabet
EDIT: although I was hoping there was a more general form of "pangram" for any case that is a "complete example" or something similar, the original impetus for this request was to describe a Markdown document that contained all examples of Markdown syntax to use as a complete test case for a set of CSS styles. Perhaps there is a name for this in the particular domain of programming/markup languages?
