This is about 2^n, not n^2. 2^0 is 1, which does not fit "all digits are even".

- 1970-01-01 2y agoNo, the sequence is "Powers of 2 with all even digits."
- CrazyStat 2y ago0^2 is a power of 0, not a power of 2.

- CrazyStat 2y agoThat list includes 2^0 = 1, which is odd. It does not include 0^2.
- layer8 2y agoYou are thinking of squares, not of powers of 2.
- 1970-01-01 2y agoI see the difference in wording now, as its not very clear what they meant
- codeflo 2y agoIt's actually very clear, and there's nothing wrong with admitting you're unfamiliar with the terminology, we all were at some point.
- nickvec 2y agoSaying “powers of two” is a universal way of denoting 2^n. It’s okay to admit being wrong rather than blaming OEIS for being vague.
- 1970-01-01 2y agoThe phrase squared is "powers of two" is much, much more common than you know. I'm part-time substituting as a grade-school teacher. Ask any if they are explaining this difference.
- ABS 2y ago"power of two" with "power" singular perhaps but "powers of two" with the word "powers" plural is really not common as a synonym of squared (excluding people who don't know what they mean at all in the first place)
