AbstractWe identify ℝ7as the pure imaginary part of octonions. Then the multiplication in octonions gives a natural almost complex structure for the unit sphereS6. It is known that a cone over a surfaceMinS6is an associative submanifold of ℝ7if and only ifMis almost complex inS6. In this paper, we show that the Gauss-Codazzi equation for almost complex curves inS6are the equation for primitive maps associated to the 6-symmetric spaceG2=T2, and use this to explain some of the known results. Moreover, the equation forS1-symmetric almost complex curves inS6is the periodic Toda lattice, and a discussion of periodic solutions is given.
