The fax numbers of the beast, and other mathematical sports

Strange. In the article A138563 is described as a sequence of prime numbers that contain the substring 667. But these are obviously not prime numbers. Having a look at https://oeis.org/A138563 reveals that these are simply any numbers containing the substring.

https://oeis.org/ is the page, interestingly enough https://oeis.org/A000001 is not the "positive integers" - that's https://oeis.org/A000027

I don’t know anybody who would both appreciate the fax number of the beast joke and not turn it into a conversation about 617 being the real fax number of the beast according to most manuscripts.

I can't tell which of Chai Wah Wu's submissions the interviewer was referring to. https://oeis.org/search?q=Chai%20Wah%20Wu&fmt=short&sort=cre...

667 - “fax number of the beast” - that was funny ;) The thing about mathematics is that it can tickle your brain - in a creative way.

It's becoming increasingly difficult these days, with so many things competing for your attention and "brain-deadening" you. It was a wonderful thing to be bored and play around with math. My favorite moments were the epiphany - that there is some hidden connection between math areas or something got new meaning.
