The Heinz number of an integer partition (y_1, ..., y_k) is prime(y_1) * ... * prime(y_k).

Examples

			Tetrangle begins (zeros not shown):
  (1):  1
.
  (2):  -1  1
  (11):     1
.
  (3):    2 -3  1
  (21):     -1  1
  (111):        1
.
  (4):    -6  3  8 -6  1
  (22):       1    -2  1
  (31):          2 -3  1
  (211):           -1  1
  (1111):              1
.
  (5):     24 30 20 15 20 10  1
  (41):       -6     3  8 -6  1
  (32):          -2  3  2 -4  1
  (221):             1    -2  1
  (311):                2 -3  1
  (2111):                 -1  1
  (11111):                    1
For example, row 14 gives: 12e(32) = -2p(32) + 3p(221) + 2p(311) - 4p(2111) + p(11111).
