You might like to consider the various formulae for the nth prime. Ie
p(n) is the nth prime. For example,
@ARTICLE{Williams1964,
AUTHOR = "Williams, C.~P.",
TITLE = "On Formulae for the $n$th Prime Number",
JOURNAL = "The Mathematical Gazette",
YEAR = "1964",
volume = "48",
number = "366",
pages = "413--415",
month = "December",
}
Then P:={p(n),n=1,2,...} does not change over time.
