/Gallivan fold

In origami, a Gallivan fold, or g-fold, :== a genus of paper folding. The paper (a 2-brane) can fold in either single or alternating direction [each must adhere to its own equation (width versus length)], and the fold phenomenon is always one-half (1/2) of the folding direction. It is based on - and named after - the paper folding theorem of Britney Gallivan.
