Is sequence A175150 ever negative?
In other words, is there an n where
(the number of k <= n where d(k) < d(k-1))
is greater than
(the number of k <= n where d(k) > d(k-1)),
where d(k) is the number of divisors of k?
PS: I see that I made a typo in the comment line to A175150. I'll go fix that now.
Thanks,
