Blaise Pascal published the workings of a triangular array showing the relationship between binary coefficients in said triangle. For instance:
__________________________________________
|.......................................1.........................................|
|..................................1........1....................................|
|..............................1.......2........1...............................|
|..........................1......3........3.......1...........................|
|......................1......4.......6.......4......1........................|
|...................1......5.....10....10......5......1...................|
|...............1......6.....15....20.....15.....6.....1...............|
|_________________________________________|
Each number in the above triangle is the sum of the two numbers right about it.
For example, 20 is the sum of 10 and 10, and 2 is the sum of 1 and 1.
