My thanks to all, who computed these, including Susanne.

Could either of you guys create this new sequence and link it to A233281 ?
(If you have free time, I mean ;-) Just now I feel a bit burn-out with
all the sequences. And you already have the data:
http://chesswanks.com/num/a233281composites.txt

And then, A233281 will be the union of A092395 and that new sequence.


Yours,
Antti Karttunen

I know we have conjectured such and it is certainly how I derived my numbers, and I assume it is how you derived yours. Without that, for what it's worth, I am (by way checking all numbers between) confirming that 162133 is indeed term #4. Thank you Susanne for reaffirming term #3.
