Weba(n) is the number of permutations of [n] that avoid the consecutive patterns 123 and 132. Proof. Write a self-inverse permutation in standard cycle form: smallest entry in each cycle in first position, first entries decreasing. For example, (6,7)(3,4)(2)(1,5) is in standard cycle form. Then erase parentheses. WebAdding all the elements of a matrix to itself would be the same as multiplying every cell in the matrix by 2, or multiplying the matrix itself by 2. You don't need to worry about the dimensions lining up because you are adding the same matrix to itself, and then you would simply multiply every cell in the matrix by 2. ( 2 votes) Luis Ocasio
