[phillip1882]

1+ the product of two squares

[ratammer]

I don't think 36 is the product of two squares, so that's not right for 37. Therefore, we restart.

[phillip1882]

36 is 4*9

[ratammer]

You're right, I must have not been paying attention when I did that post. Still, I've restarted now, so we carry on from the restart as per the rules.

I restarted from zero, and you moved on to two... so we restart again.

The number of elements in the empty set.

[Sean Quixote]

Just for future reference, I'm gonna go ahead call an audible here, and decree/clarify that starting over from zero is not required. (I was just trying to be silly when beginning it that way.) Starting from either one or zero are both perfectly acceptable, so if people do it in the future, don't declare that they were wrong and start over yet again. (I also know that isn't what happened a couple posts ago -- ratammer was doing it "right" by being vigilant -- I'm just saying, if it does happen we should just proceed normally.) But, also, note that I'm not going to edit the OP to reflect this, because, I dunno, reasons or something.

Anyway...


This number yields 55 if you decode it from base64 and then convert the binary value back to decimal.
