[seqfan] Re: A064736, A217579 and A302350

[Neil Sloane]

well of course ideally the best way is to use the Index entry

permutations of the positive (or nonnegative) integers , sequences related
to :

but that is probably not up to date

To make it more up-to-date, we need to add more A-numbers to
that Index, and we need to add more
links to the Index from those A-numbers. Here is the link to add:

<a href="/index/Per#IntegerPermutation">Index entries for sequences that
are permutations of the natural numbers</a>

which I took from the classic permutation A006368.
