 OFFSET 0,1 COMMENTS Data generated using MATLAB. LINKS Seiichi Manyama, Table of n, a(n) for n = 0..1000 EXAMPLE 26^2 + 1 == 677 (mod 10^3), 677^2 + 1 == 330 (mod 10^3), 330^2 + 1 == 901 (mod 10^3), 901^2 + 1 == 802 (mod 10^3), 802^2 + 1 == 205 (mod 10^3), and 205^2 + 1 == 26 (mod 10^3), so 6 2 0 comprise the sequence's first three terms.
