			Tetrangle begins (zeroes not shown):
  (1):  1
.
  (2):  -1
  (11):  1  2
.
  (3):    1
  (21):  -1 -1
  (111):  1  3  6
.
  (4):    -1
  (22):    1  2

.
  (5):      1
  (41):    -1 -1
  (32):    -1    -1
  (221):    1  1  2  2
  (311):    1  2  1     2
  (2111):  -1 -3 -4 -6 -6 -6
  (11111):  1  5 10 30 20 60 20
For example, row 14 gives: p(32) = -f(5) - f(32).
