%N A292994 Number of integers m, 1 <= m <= A002569(n), that are not terms in the triangle T(n,k) of A008284.
%e A292994 With n = 10, the maximum value of m is 9 and all values of m from 1 to 9 appear within the first 10 rows of A008284, so a(10) = 0.
%e A292994 With n = 13, the maximum value of m is 18 and all values of m from 1 to 18, except 16 and 17, appear within the first 13 rows of A008284, so a(13) = 2.
