Articles are grouped in sections on arithmetic, primes, irrationality and continued fractions, sums of squares and polygonal numbers, Fibonacci numbers, number-theoretic functions, and elliptic curves, cubes, and Fermat's last theorem.
Now we define two new number-theoretic functions U(n) and V (n) as following,
From the point of view of classical mathematics, there are uncountably many sets of natural numbers and uncountably many number-theoretic functions. Since the finitist (meta-)mathematician probably refuses to allow the postulation of uncountably many figures, he will not have enough figures at his disposal for "coding" all number-theoretic functions.
