The catakleismic temperament is one of the best extensions of hanson, the 5-limit temperament tempering out the kleisma.
Catakleismic is naturally viewed as a 2.3.5.7.13 temperament, first extending hanson to include the harmonic 13 (called cata), and then to include 7. Various reasonable extensions exist for harmonic 11. These are undecimal catakleismic, mapping 11 to -21 generator steps, cataclysmic, to +32 steps, catalytic, to +51 steps, and cataleptic, to -2 steps.
See Kleismic family #Catakleismic for technical data.
