	OFFSET	`1,5`
	COMMENT	`The first two are zero because the Ulam sequence (A002858) is initialized for those terms. The terms of the sum are in A080328 and A080329, and the indices are in A080330 and A080331.`
	EXAMPLE	`The 11th Ulam number (26) is the sum of the 6th Ulam number (8) and the 10th Ulam number (18), so a(11)=6.`
	CROSSREFS	`Cf. A002858, A080328, A080329, A080331.` `Adjacent sequences: A080327 A080328 A080329 this_sequence A080331 A080332 A080333` `Sequence in context: A105560 A096013 A072380 this_sequence A072832 A080328 A031266`
