	OFFSET	`0,3`
	COMMENT	`This is the size of the cycle containing A080980(n) in the permutations A057505/A057506.` `If the conjecture given in A080070 is true, then this sequence contains only six 2's. Questions: are there any (other) values with finite number of occurrences? Which primes will eventually appear?`
	FORMULA	`a(n) = A080967(A080980(n))`
	CROSSREFS	`Cf. A080969, A080972.` `Sequence in context: A029093 A078462 A157501 this_sequence A115733 A025496 A099959` `Adjacent sequences: A080965 A080966 A080967 this_sequence A080969 A080970 A080971`
