A049298

Take reduced residue systems of n, generate its first differences, dRRS(n); sequence gives maximal value of dRSSS(n).

	OFFSET	`1,3`
	COMMENTS	`Greatest values occur at primorial numbers (A002110).`
	EXAMPLE	`If n is prime, its reduced residue system consists of all numbers below n. But the difference 2 arises from d=1-(n-1)=-n+2 (mod n).`
	CROSSREFS	`Cf. A048670. Essentially same as A048669.` `Sequence in context: A027387 A111735 A102298 * A075016 A102445 A027389` `Adjacent sequences: A049295 A049296 A049297 * A049299 A049300 A049301`
