COMMENTS
Row n has length A000041(A056239(n)).
The Heinz number of an integer partition (y_1, ..., y_k) is prime(y_1) * ... * prime(y_k).
We define the augmented Schur functions to be S(y) = |y|! * s(y) / syt(y), where s is Schur functions and syt(y) is the number of standard Young tableaux of shape y.

EXAMPLE
Triangle begins:

1
1 1
-1 1
2 3 1
-1 0 1
6 3 8 6 1
2 -3 1
0 3 -4 0 1
-2 -1 0 2 1
24 30 20 15 20 10 1
2 -1 0 -2 1
120 90 144 40 15 90 120 45 40 15 1
-6 0 -5 0 5 5 1
0 -6 4 3 -4 2 1
-6 3 8 -6 1
720 840 504 420 630 504 210 280 105 210 420 105 70 21 1
0 6 -4 3 -4 -2 1
For example, row 15 gives: S(32) = 4p(32) - 6p(41) + 3p(221) - 4p(311) + 2p(2111) + p(11111).
