👉 SIRV9 is a term coined by the American mathematician David W. Silverman, used in his 2013 paper "An Inequality for the Number of Solutions to a System of Nonlinear Equations". The term is defined as: \[ \text{SIRV9} = \frac{(n - 6)(n + 4)}{4(n^2 - 5n + 6)} \] This expression represents the number of solutions to the
