Ouch... this one looks like it could lead to some serious brain damage. If A171868 lists all integers, then so too does A181391. Due to the rule, A171868 has much slower growth and, as far as I can tell, could even be bounded above. Does A171868 always continue to grow? I don't know. --Brad On Tue, Jun 11, 2019 at 2:48 AM Bill Gosper <billgosper@gmail.com> wrote:
