    Your observation that we're trying to "get rid of redundancy" actually provides ample motivation for students with an applications bent. I'm an advocate of pure math, yet even I was appreciated the insight. New subscriber here. Thank you.

      @@vector8310 Very nice of you to notice. Most of my students are not pure math majors, so I'm always trying to reach across the aisle.

    Thanks. It was just what I needed to understand it. What is the spelling of the notation name please? It sounds like you say "kochi's" notation?

    Hello
    Is it possible to express (1 2 3 4) in S4 as a product of disjoint cycles ?
    Thanks

    • @AdamGlesser
      @AdamGlesser  7 หลายเดือนก่อน +1

      Yes, but you may not like the answer. Because (1 2 3 4) is already a cycle with no repetitions, we consider it a product of disjoint cycles. I suspect you really want to know if we can write (1 2 3 4) as a product of two (or more) disjoint cycles. The answer to that is no. This is because, up to reordering the disjoint cycles, we can write any permutation as a product of disjoint cycles in only one way. Since (1 2 3 4) is already one such way, there are no others.

    sir one doubt
    in ans a
    there is only one cycle we got so this is the disjoint cycle right

    • @AdamGlesser
      @AdamGlesser  3 ปีที่แล้ว

      That's right. In order to make the language easier, we allow for "product of disjoint cycles" to include there being a single cycle. In fact, we even allow it to mean zero cycles. For example (1 2)(1 2) equals the identity permutation which, if forced do so, we would refer to as the empty product of disjoint cycles.
