|
|
FORMULA
|
A140579 as an infinite lower triangular matrix * A008683 as a vector, where A008683 = the mu sequence and A140579 is a diagonalized matrix version of A014963. Given the A008683, the mu sequence (1, -1, -1, 0, -1, 1, -1, 0, 0, 1,...), replace (-1) with (-n). Other mu(n) remain the same.
|
|
EXAMPLE
|
Replacing any (-1) with (-n), we get (1, -2, -3, 0, -5, 1, -7, 0, 0, 1,...).
