%N The 10-adic integer a = ...580984952634 satisfying a^3 + 1 = b, b^3 + 1 = c, c^3 + 1 = d, and d^3 + 1 = a.

%C There is one other automorphic cube-ring of four 10-adic integers.

%H Seiichi Manyama, <a href="/A317698/b317698.txt">Table of n, a(n) for n = 0..1000</a>

%e 634^3 + 1 == 105 (mod 10^3), 105^3 + 1 == 626 (mod 10^3), 626^3 + 1 == 377 (mod 10^3), and 377^3 + 1 == 634 (mod 10^3), so the sequence begins 4 3 6.

%Y Cf. A318299 (b), A318300 (c), A318302 (d).

%Y Cf. A318135, A318136, A318137, A318138, A318139, A318140.
