This is a table of values for Euler's totient function,
also known as Euler's phi function.
This function counts the positive integers up to a given integer, n, that
are relatively prime (coprime) to n.
My existing table in David Burton's excellent book,
“Elementary Number Theory”,
has a table for the first one hundred integers.
The table here goes up to 2459.
