Strictly Decreasing Sequence: Also known as
A strictly decreasing sequence is also referred to as strictly order-reversing.

Some sources use the term descending sequence or strictly descending sequence.

Some sources refer to a strictly decreasing sequence as a decreasing sequence, and refer to a decreasing sequence which is not strictly decreasing as a monotonic decreasing sequence to distinguish it from a strictly decreasing sequence.

That is, such that monotonic is being used to mean a decreasing sequence in which consecutive terms may be equal.

does not endorse this viewpoint.
