I looked up the Chinese original to make sure I understood it. What the noble one does is to 定其交而后求 –‘He settles and makes sure of ( ding, 定) his jiao 交, and-then-afterwards asks.’ Starting with the ones digit of the bottom number, the multiplier, multiply it by the last digit in the top number I the LORD have called thee in righteousness, And have taken hold of thy hand, And kept thee, and set thee for a covenant of the people, For a light of the nations;

These numbers are extremely rare, much more so than prime numbers: only 14 of the former are lower than one billion. Catalan numbers were first mentioned, under another name, by Swiss mathematician Leonhard Euler, who wanted to know how many different ways an n-sided convex polygon could be cut into triangles by connecting vertices with line segments. The beginning of the sequence ( A000108 in OEIS) is 1, 1, 2, 5, 14, 42, 132.... The nth element of the sequence is given by the formula c( n) = (2 n)! / ( n!( n + 1)!). And like the two preceding sequences, the density of numbers is null at infinity. I the Lord God have called thee in righteousness, and will hold thine hand, and will strengthen thee: and I have given thee for the covenant of a race, for a light of the Gentiles:
