Two new formulas for triangulation number T.
The present paper reports two new formulas for calculating triangulation number T. T = L2/l2 and T = 1.45 r2/l2, where L is the distance between pentons, l the distance between any two adjacent capsomeres, r the radius of viral nucleocapsid. The formulas have been verified and applied. It is worth noticing that the triangulation number, viral size and distance between capsomeres are fully connected by the formula r/the square root of Tl = 0.83, and the capsid parameters of all icosahedral viruses are unified in one constant, 0.83.
