Predefined Geometric Algebras

clifford provides several predefined algebras,

• g2 : 2D Euclidean

• g3 : 3D Euclidean

• g4 : 4D Euclidean

• g2c : Conformal space for G2 (G3,1)

• g3c : Conformal space for G3 (G4,1)

You can use them like so

from clifford import g2

g2.e1*g2.e2

(1^e12)

The layout and blades are also available,

g2.layout

Layout([1, 1],
       [(), (1,), (2,), (1, 2)],
       names=['', 'e1', 'e2', 'e12'],
       firstIdx=1)

g2.blades

{'': 1, 'e1': (1^e1), 'e2': (1^e2), 'e12': (1^e12)}

Or, specifically import the blades you need for your app

from clifford.g2 import e1,e2,e12
e1*e2==e12

True
