Write the longest period iterating quine bounded by 500 bytes

$begingroup$


Your job is to create the longest period iterating quine, where the length of each program in the sequence is bounded by 500 bytes.



That is, if you repeat the following steps:




  1. Start with your initial program

  2. Run the current program

  3. Go back to step 2


You will eventually get back to your original program. The number of programs in the cycle is your score, which you are trying to maximize.



None of the programs may raise any errors. Each program must be run the same way as well (e.g. no different versions, implementations, compiler options, platforms, etc...).



What separates this challenge from The longest period iterating quine (other than 100 v.s. 500) is that every program in the cycle must also be 500 bytes or less. This means that the longest possible cycle is (256^501 - 1)/255 or less. That of course is a big number, but not that big in terms of how much code it takes to calculate. So the challenge is about using as many of the (256^501 - 1)/255 possibilities as you can, not a busy beaver challenge.



The programs are not permitted to access its own source code. However an empty program is permitted if you want (as long as you follow the other rules).



Since checking the programs manually would be hard, you may figure out the score using theoretical methods. You must include an explanation of the score and correctness with your program. If you can not figure out the score, you may instead use a lower bound of the number of programs in the cycle as a defacto score. You are allowed to update this as you find better lower bounds, or if you find the exact actual score.



This is code-challenge, so highest score wins!

    @KrystosTheOverlord no there is no code golf. However, I expect there to be a code golf like aspect, since the shorter the main program is, the more room for comments (which can make the programs distinct).

Perl 6, $126^{398}$ iterations





$!=Q~~;<say "$!=Q~{chrs(my@a=[R,] polymod :126[$!.ords]+1: 126 xx*)x?(@a-398)}~;<$_>~~.EVAL">~~.EVAL



Try it online!



This iterates through all the possible combinations of the first 126 bytes of length 397 and under (excluding strings with leading NUL bytes). If you want to see that it actually returns to the first iteration, you can reduce the length to 1 by changing the limit like so.

    This calculation suggests that you way over estimated your score. The numerator is how many strings of length 397 there are using 126 symbols. (I had to distribute the fraction into the sum since wolfram alpha was acting weird.)

Gol><>, 67 bytes



":1=l8:*4+=S&Q~P:'~'=Q~~'H'||lPaa*5*=?1:1=Q$~|:1)lPaa*5*(Q?:|r2ssHH


Basically this program replicates the H at the end, then when it reaches 499 in length, appends a char with an ascii code of 1, this begins the deletion process, then when it reaches its original length plus one, it increments the last char. Finally, if the last char is a '~', it pushes an H instead!!!



I have no idea what the score would be... Too much math for tonight, I'll figure it out tomorrow...

        Basically this program replicates the H at the end, then when it reaches 499 in length, appends a char with an ascii code of 1, this begins the deletion process, then when it reaches its original length plus one, it increments the last char. Finally, if the last char is a '~', it pushes an H instead!!!



        I have no idea what the score would be... Too much math for tonight, I'll figure it out tomorrow...

            If this is an answer to a challenge…




            • …Be sure to follow the challenge specification. However, please refrain from exploiting obvious loopholes. Answers abusing any of the standard loopholes are considered invalid. If you think a specification is unclear or underspecified, comment on the question instead.


            • …Try to optimize your score. For instance, answers to code-golf challenges should attempt to be as short as possible. You can always include a readable version of the code in addition to the competitive one.
              Explanations of your answer make it more interesting to read and are very much encouraged.


            • …Include a short header which indicates the language(s) of your code and its score, as defined by the challenge.



            More generally…




            • …Please make sure to answer the question and provide sufficient detail.


            • …Avoid asking for help, clarification or responding to other answers (use comments instead).
