Number of primes >= p(n)# and < p(n)# + p(n+1)^2 where p(i)=i-th prime, p(i)#=i-th primorial.

4, 7, 11, 21, 24, 29, 25, 38, 42, 37, 58, 54, 45, 60 (list; graph; refs; listen; history; internal format)

	OFFSET	`1,1`
	COMMENTS	`Conjecture: a(n) is alway > p(n+1)`
	EXAMPLE	`p(1)#=2 p(1)#+p(2)^2=11 2 3 5 7 are >=2 and <11 so a(1)=4` `p(2)#=6 p(2)#+p(3)^2=31 7 11 13 17 19 23 29 are >=6 and < 31 so a(2)=7`
