COMMENTS

For the definition of the LG1 matrix coefficients see A162448.

We define the columns sums by cs(n) = sum(LG1[2*m,n], m = 0.. infinity) for n => 2.

LINKS

Table of n, a(n) for n=2..12.

FORMULA

a(n) = denom(cs(n)) and numer(cs(n)) = A162448(n).

CROSSREFS

See A162448 for the numerators of the column sums.
