=== Period arithmetic ===
deformation dimension = 25
period-domain dimension = 20
forced period excess = 5

Define rho_per = h^2(Y,Omega^3(H)).
Using h0=0, chi=-5, and hq=0 for q>=3:
  h1 = 5 + rho_per
  rank(dP) = 20 - rho_per
rho=0: kernel=5, period rank=20
rho=1: kernel=6, period rank=19
rho=2: kernel=7, period rank=18
