The **Kodaira symbol** encodes the reduction type of an elliptic curve at a prime $p.$ It describes the combinatorics of the special fiber of the Néron model of the elliptic curve. The Néron model is obtained from the minimal Weierstrass equation using Tate's algorithm. For an exact definition and properties, consult a text on elliptic curves.
