%C Indices where this sequence is 0 form the sequence A370277.

%C The indices of record high values form the sequence A370279.

%e For n = 6, floor(k^(2/3)) = 3, but for all triples (a_1, a_2, a_3), there is a choice of p such that |p*a_1| mod 6, |p*a_2| mod 6, and |p*a_3| mod 6 are all smaller than or equal to 2.

%e For example, consider the triple (1, 2, 3), with p = 2; we have:

%e |2 * 1| mod 6 = 2, |2 * 2| mod 6 = 2, and |2 * 3| mod 6 = 0.

%e Note that there is no nonzero choice of p such that all values are smaller than 2 for this triple.

%Y Cf. A370277, A370279.
