The Heinz number of an integer partition (y_1, ..., y_k) is prime(y_1) * ... * prime(y_k).
Also the coefficient of e(v) in f(u), where f is forgotten symmetric functions and e is elementary symmetric functions.

EXAMPLE
Tetrangle begins:
(1): 1
.
(2): 2 -1
(11): -1 1
.
(3): 3 -3 1
(21): -3 5 -2
(111): 1 -2 1
.
(4): 4 -2 -4 4 -1
(22): -2 3 2 -4 1
(31): -4 2 7 -7 2
(211): 4 -4 -7 10 -3
(1111): -1 1 2 -3 1
.
(5): 5 -5 -5 5 5 -5 1
(41): -5 9 5 -7 -9 9 -2
(32): -5 5 11 11 -8 10 -2
(221): 5 -7 11 14 10 14 3
(311): 5 -9 -8 10 12 13 3
(2111): -5 9 10 14 13 17 -4
(11111): 1 -2 -2 3 3 -4 1
For example, row 14 gives: m(32) = -5h(5) + 11h(32) + 5h(41) - 11h(221) - 8h(311) + 10h(2111) - 2h(11111).
