reordering

Cyclically rotate the digits within each integer by a chosen number of positions.

Cyclically rotate the order of a list of integers by a chosen number of positions.

Output the list followed by the list reversed, so item order becomes a palindrome.

Rotate a list left or right by N positions with true wrap-around, e.g. [1,2,3,4] left 1 becomes [2,3,4,1].
