	OFFSET	`1,1`
	COMMENT	`To construct the sequence use the rule : a(1)=3, then a(a(1)+a(2)+...+a(n)+1)=2+(-1)^n and fill in any undefined place with 2.`
	FORMULA	`a(n)=(1/2)*(1+A004200(n+1)); a(a(1)+a(2)+...+a(n)+1)=2+(-1)^n`
	EXAMPLE	`Example to illustrate the comment : a(a(1)+1)=a(4)=2+(-1)^1=1 and a(2), a(3) are undefined. The rule forces a(2)=a(3)=2.`
	CROSSREFS	`Cf. A088431.` `Sequence in context: A065310 A016558 A090341 this_sequence A074976 A068448 A054081` `Adjacent sequences: A088432 A088433 A088434 this_sequence A088436 A088437 A088438`
