%N Triangle read by rows: T(k,m) = number of occurrences of k in the last section of the set of partitions of (10 + m).

%C Sub-triangle of A182703 and also of A194812. Note that the sum of row k is also the number of partitions of 10. For further information see A182703 and A135010.

%F T(k,m) = A182703(10+m,k), with T(k,m) = 0 if k > 10+m.

%F T(k,m) = A194812(10+m,k).

%F Beginning with row k=11 each row starts with (k-11) 0's and ends with the subsequence 1, 0, 1, 1, 2, 2, 4, 4, 7, 8, 12, the initial terms of A002865. - Alois P. Heinz, Feb 15 2012

%e ....

%e For k = 1 and m = 1; T(1,1) = 42 because there are 42 parts of size 1 in the last section of the set of partitions of 11, since 10 + m = 11, so a(1) = 42. For k = 2 and m = 1; T(2,1) = 15 because there are 15 parts of size 2 in the last section of the set of partitions of 11, since 10 + m = 11, so a(2) = 15.

%Y Always the sum of row k = p(10) = A000041(10) = 42.

%Y The first (0-10) members of this family of triangles are A023531, A129186, A194702-A194709, this sequence.

%Y Cf. A002865, A135010, A138121, A194812.
