Also the first row A194833(1, n) = a(n). This can be seen in the EXAMPLE section of A372341. Each row is horizontally shifted by a value from A005206. The shift is known to be floor((k+1)*tau)-k-1, where tau is the golden ratio. The position of "1" in a permutation from A194832 is determined by a similar process based on the same constant. - _Thomas Scheuerle_, Jul 08 2024 %e A372231 A372341(49) = 49, so 49 belongs to this sequence. %o A372231 (C++) // See Links section. %Y A372231 Cf.
