	OFFSET	`1,1`
	COMMENT	`Also, number of primes between p(n) and p(p(n)) inclusive, where p(k) is the k-th prime. - Zak Seidov (zakseidov(AT)yahoo.com), Sep 22 2003` `Since a(n+1)-a(n)=p(n+1)-p(n)-1>=1 the sequence is monotonic.`
	EXAMPLE	`p(1) = 2, p(p(1)) = p(2) = 3 and there are two primes between 2 and 3 inclusive.`
	CROSSREFS	`Equals A014689 + 1.` `Sequence in context: A088633 A114952 A086969 this_sequence A058670 A091605 A145468` `Adjacent sequences: A014689 A014690 A014691 this_sequence A014693 A014694 A014695`
