Summary: Examples of \(d\)-perfect sequences are constructed based on the method in [C. Xing and K. Y. Lam, IEEE Trans. Inf. Theory 45, 1267-1270 (1999; Zbl 0943.94008); C. Xing, H. Niederreiter, K. Y. Lam and C. Ding, Finite Fields Appl. 5, 301-313 (1999; Zbl 0943.94005)]. In particular examples of 1-perfect sequences based on genus 0 curves over binary and the ternary fields are computed, as are 2-perfect binary sequences based on an elliptic curve. The complexity profile of certain of the 2-perfect sequences are experimentally determined to follow that of 1-perfect sequences. Based on two algebraic reformulations of the known characterization of binary 1-perfect sequences, these sequences are proved to be 1-perfect.
