 A091767 a(n) is the largest number such that all numbers from 1 to a(n) can be expressed using first n terms of A091766. 1
 1, 3, 8, 9, 10, 11, 17, 19, 21, 27, 28, 31, 38, 42, 43, 44, 51, 52, 54, 55, 57, 58, 61, 68, 73, 74, 75, 76, 77, 89, 93, 94, 95, 97, 102, 103, 111, 112, 114, 115, 117, 118, 119, 123, 124, 126, 138, 144, 145, 146, 147, 153, 156, 161, 174, 175, 176, 177, 180, 182, 184, 185 (list; graph; refs; listen; history; text; internal format)
 OFFSET 1,2 LINKS EXAMPLE Using first three terms 1,2 and 6 of A091766, all numbers up to 8 can be obtained in this manner. (1), (2), (3=1+2), (4= 6-2), (5=6-1), (6), (7=6+1), (8=6+2), hence a(3) = 8. CROSSREFS Cf. A091766, A000244.
