== Was that a good idea? ==
Line 20 ⟶ 22:
::It can also become ponderous to add all the side conditions in prose. Is the base case {{math|1=''i''=0}} or {{math|1=''i''=1}}? Is a theorem true for all primes, or only odd primes? Are negative integers included? Must the triangle be non-degenerate? It's not that such things can't be expressed in prose, but rather that they obscure the explanation. I like to include an informal description which omits such minor details in order to focus on the main idea, and include the details (which are necessary for correctness) in the formal description.

:::Such a thing might be helpful later in the article, but technicality is not good for the lead. By the way, I'm not convinced that (row, column) is the simpler way to index these things, at least for infinite triangles (the case mainly considered here). (column,row - column) with zero-based indexing gives a scheme in which the row is easily recovered as the sum of the two coordinates and in which the only condition is that both coordinates are non-negative.
