EXAMPLE
|
After a(40) = 660 we have that in the sequence A299773 the terms A299773(661)..A299773(671) are less than A299773(660) = 7187172406818511650939943511021032181119077585. The next term greater than A299773(660) is A299773(672) = 7187180892191062904110726467218877665371246875, so a(41) = 672. Note that both 660 and 672 have the same number of divisors (tau(660) = tau(672) = 24) and the same sum of divisors (sigma(660) = sigma(672) = 2016).
