Sloane's Gap. Mathematical and Social Factors Explain the Distribution 
of Numbers in the OEIS
Nicolas Gauvrit, Jean-Paul Delahaye, Hector Zenil

The Online Encyclopedia of Integer Sequences (OEIS) is made up of
thousands of numerical sequences considered particularly interesting
by some mathematicians. The graphic representation of the frequency
with which a number n as a function of n appears in that database
shows that the underlying function decreases fast, and that the points
are distributed in a cloud, seemingly split into two by a clear zone
that will be referred to here as "Sloane's Gap". The decrease and
general form are explained by mathematics, but an explanation of the
gap requires further considerations.
