New XKCD Forums

I was just counting on discord, and came across https://xkcd.com/2016/:



Sounds like fun. I'll try and come up with a couple....




sub[1]: a(n)= n × t, where n is an OEIS serial number, and t is the Unix epoch at the time of that sequence's publication to the website.

sub[2]: The number of values in the sequence of serial number n, or 0 if it is unknown, or -1 if it is infinite, multiplied by the Unix epoch at the time of that sequence's publication to the website.

sub[3]: The real part(s) of the imaginary part(s) of all the sequences I was intending on coming up with before submitting this post, but gave up instead because it turned out to be too much effort... (Note: they are, and will remain, "imaginary", for the time being, because I didn't articulate them.)

sub[4]: Each value of the previous sequence, multiplied by the Unix epoch at the time(s) that it would have been had I put forth the effort.

sub[5]: the set of numbers that represent a gaseous sound when applied to a music player.
sub[6]: the set of numbers that are a sum of banking committee registration codes.
sub[7]: the set of numbers that can be represented by four dimensional chess.
