Descent algebras, rising sequences, and a good card trick done poorly, if at all

We will take a short look at how one might model card shuffling with permutations. This leads to a study of the descent algebra, and finally we will introduce a subalgebra (close to my heart) known as the peak algebra. We find a lovely connection between the peak algebra and descent algebra and explore some of its properties.
