%N A376667 Square array read by antidiagonals: row n lists numbers whose maximal frequency in a fixed row of A036038 (or A078760) is equal to n, i.e., numbers m such that A376663(m) = n.
%C A376667 In case there are only finitely many solutions for a certain value of n, the rest of that row is filled with 0's.
%C A376667 Each positive integer appears exactly once in the array, so as a linear sequence it is a permutation of the positive integers (unless there are any 0's).
