A160469
A "look-alike" of the numerators in Taylor series for tan(x).
This sequence makes its appearance as the first left hand column of 'triangle' A160468.
The first difference with the sequence for the numerators in the Taylor series for tan(x) A002430 occurs at a(12). Its resemblance with this sequence led to the conjecture A160469(n) = A002430(n)*A089170(n-1).
