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

Examples

			Tetrangle begins (zeroes not shown):
  (1):  1
.
  (2):   1
  (11): -1  1
.
  (3):    1
  (21):  -1  1
  (111):  1 -2  1
.
  (4):     1
  (22):       1 -1
  (31):   -1     1
  (211):   1 -1 -1  1
  (1111): -1  1  2 -3  1
.
  (5):      1
  (41):    -1  1
  (32):       -1  1
  (221):       1 -1  1 -1
  (311):    1 -1 -1     1
  (2111):  -1  1  2 -2 -1  1
  (11111):  1 -2 -2  3  3 -4  1
For example, row 14 gives: s(32) = h(32) - h(41).
