COMMENTS
The Heinz number of an integer partition (y_1, ..., y_k) is prime(y_1) * ... * prime(y_k).
Also the coefficient of f(v) in h(u), where f is forgotten symmetric functions and h is homogeneous symmetric functions.
EXAMPLE
Tetrangle begins (zeroes not shown):
(1): 1
.
(2): 1
(11): 1 2
.
(3): 1
(21): 1 3
(111): 1 3 6
.
(4): 1
(22): 1 2 6
(31): 1 4
(211): 2 1 5 12
(1111): 1 6 4 12 24
.
(5): 1
(41): 1 5
(32): 1 3 10
(221): 1 5 2 12 30
(311): 2 1 7 20
(2111): 1 3 12 7 27 60
(11111): 1 5 10 30 20 60 20
For example, row 14 gives: e(32) = m(221) + 3m(2111) + 10m(11111).
