COMMENTS
T(n,k) is square 1 <= k <= n.
Alternative triangle construction: Write each column k as each square repreated k times.
T(*,1) is A000290.
T(*,2) is A008794.
T(*,3) is A211547.
T(*,4) is A295643(n+4).
T(*,5) is A287392(n+1).
Row sums of triangle are A222548.
This assumes the sides of the small squares are parallel to those of the large square. If the small squares are allowed to be rotated, better packings may exist (see e.g. the Friedman link).
