	OFFSET	`1,2`
	FORMULA	`a(n)=Prime[n]^2 - Max[q], where Max[q] is the largest prime preceding n-th prime-square.`
	EXAMPLE	`n=4 and p(4)^2=49, preceded by 47 in the minimal distance, 2 so a(4)=2. n=97 and p(97)^2=509^2=259081, just preceded by 259033=p(22765) in a hihgher(=48) distance from the p-square, so a(97)=48.`
