Answer 1

We have list [x: y: z]. The sheet always counts from x to y in increments of z (default is z = 1). If x or y has a negative sign, then their position is counted from the end of the list. The first element of the list has position 0, the last element of the list has position - 1. If x and y refer to the same element, we get an empty list []
