https://ask.sagemath.org/question/66814/what-is-a-first-and-second-element-of-secp256k1/?answer=66820#post-id-66820The order of `secp256k1` is odd (see [here](https://ask.sagemath.org/question/61893/)), and so there are no points of even order, including order 2. The only order-1 point is the (additive) identity element `(0 : 1 : 0)`.
I'm not sure what are "first" and "second" elements you refer to.Tue, 07 Mar 2023 01:03:05 +0100https://ask.sagemath.org/question/66814/what-is-a-first-and-second-element-of-secp256k1/?answer=66820#post-id-66820Comment by Max Alekseyev for <p>The order of <code>secp256k1</code> is odd (see <a href="https://ask.sagemath.org/question/61893/">here</a>), and so there are no points of even order, including order 2.
