f97090c997 Try a cut that goes through the trivial solution
The previous cut was supposed to do this, but I was missing some parentheses.

45aaaafc8f Seek sample solutions by cutting with a hyperplane
The example hyperplane yields a single solution, with multiplicity six. You can
find it analytically by hand, and homotopy continuation finds it numerically.

a3f3f6a31b Order spheres before points within each coordinate block
In the cases I've tried so far, this leads to substantially smaller
Gröbner bases.

65d23fb667 Use module names as filenames
You're right: this naming convention seems to be standard for Julia
modules now.

6349f298ae Extend AbstractAlgebra ideals to rational coefficients
The extension should also let us work over finite fields of prime order,
although we don't need to do that.

c29000d912 Write a simple solver for the hitting set problem
I think we need this to find the dimension of the solution variety.

86dbd9ea45 Order variables by coordinate and then element
In other words, order coordinates like
  (rₛ₁, rₛ₂, sₛ₁, sₛ₂, xₛ₁, xₛ₂, xₚ₃, yₛ₁, yₛ₂, yₚ₃, zₛ₁, zₛ₂, zₚ₃)
instead of like
  (rₛ₁, sₛ₁, xₛ₁, yₛ₁, zₛ₁, rₛ₂, sₛ₂, xₛ₂, yₛ₂, zₛ₂, xₚ₃, yₚ₃, zₚ₃).

In the test cases, this really cuts down the size of the Gröbner basis.

660f42b31f Automatically generate externals.js from package-lock.json
This commit adds a utility to parse package-lock.json and write the proper
  contents of externals.js to standard output. In addition, if the utility
  (src/helpers/pkglock_to_externals.litcoffee) is invoked with a --doc option,
  it instead emits a Markdown bulleted list of all of the external dependencies.
