# kappaDivisorM0nbar -- the class of the divisor kappa

- Usage:
    `kappaDivisorM0nbar(14)`
- Inputs:
  - n, an integer,
- Outputs:
  - D, an instance of the type SymmetricDivisorM0nbar,

## Description

On $\bar{M}_{0,n}$, the divisor kappa may be defined by $K + \Delta$, where $K$ is the canonical divisor, and $\Delta$ is the sum of the boundary classes $B_i$. A fun fact is that kappa . $F_{I_1,I_2,I_3,I_4} =1$ for every F curve.
