Hello,
I've listed some sequences in context (at least in reference to
floretions) under:
http://www.crowdog.de/Zone.html
In particular, we find Antti Karttunen's nice sequence
A033539 : Number of times certain simple recursive programs call
themselves.
A024537 is then found in the same batch (see "em[J*]" down the page).
There are also a few unlisted sequences. Unfortunately, I see that the
first term of several sequences are "wrong" - they can probably just be
ignored. I'm almost positive that the wrong intitial terms are due to my
program code (for example, a cyclic transform i -> j , j->k , k-> i
which is used may come "one step too early" in the code. In principle,
it is not necessary to use a cyclic transform as the recurrence relation
is not greater than order 4 ; I just used it in order to find the
sequences involved as quickly as possible). Hope this helps a bit.
Sincerely,
Creighton
It's a shame when the girl of your dreams would still rather be with
someone else when you're actually in a dream.
