 OFFSET 1,1 COMMENTS This is the fourth of four sequences, u^v, u^v', u'^v, u'^v', that partition the positive integers. See A346308. LINKS Table of n, a(n) for n=1..54. EXAMPLE (1) u ^ v = ( 1, 5, 8, 12, 15, 19, 22, 24, 25, 29, 31, 32, ...) = A346308. (2) u ^ v' = ( 2, 4, 7, 9, 11, 14, 16, 18, 21, 26, 28, 33, ...) = A356085. (3) u' ^ v = ( 3, 6, 10, 13, 17, 20, 27, 34, 51, 58, 64, 71, ...) = A356086. (4) u' ^ v' = (23, 30, 37, 40, 44, 47, 54, 61, 68, 75, 78, 85, ...) = A356087.
