    The sequence starts with a unary operation (the successor function with n = 0), and continues with the binary operations of addition (n = 1), multiplication (n = 2), exponentiation (n = 3), tetration (n = 4), pentation (n = 5), etc. Various notations have been used to represent hyperoperations.

    The only known powers of 2 with all digits even are 2 1 = 2, 2 2 = 4, 2 3 = 8, 2 6 = 64 and 2 11 = 2048. [12] The first 3 powers of 2 with all but last digit odd is 2 4 = 16, 2 5 = 32 and 2 9 = 512. The next such power of 2 of form 2 n should have n of at least 6 digits.

    [11] [9] [12] As tends towards infinity, the difference between the harmonic numbers (+) and converges to a non-zero value. This persistent non-zero difference, ln ⁡ ( n + 1 ) {\displaystyle \ln(n+1)} , precludes the possibility of the harmonic series approaching a finite limit, thus providing a clear mathematical articulation of its divergence.

    f is continuous at any one point (Rudin, 1976, chapter 8, exercise 6). f is increasing on any interval. For the uniqueness, one must impose some regularity condition, since other functions satisfying f ( x + y ) = f ( x ) f ( y ) {\displaystyle f(x+y)=f(x)f(y)} can be constructed using a basis for the real numbers over the rationals , as ...
