EXAMPLE
|
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).
