The most important of these is tridecimal godzilla, where primes 11 and 13 are mapped such that 10/9 and 11/10 are tempered together and that 7/6, 8/7, 13/11, and 15/13 are tempered together. Semafour takes the same mapping of 13 as godzilla, but swaps in a less complex and less accurate mapping for 11, so that 4/3 and 11/8 are tempered together. Similarly, varan takes the same mapping of 13 as godzilla, but swaps in a more complex mapping for 11, so that 6/5 and 13/11 are tempered together. Finally, baragon swaps in a less complex mapping for prime 11, so that 7/5 and 11/8 are tempered together.  
Tridecimal godzilla maps prime 11 such that [[10/9]] and [[11/10]] are tempered together and that [[13/11]] is tempered together with [[7/6]]~[[15/13]]~[[8/7]] semifourth cluster. Semafour swaps in a less complex and less accurate mapping for 11, so that [[4/3]] and [[11/8]] are tempered together. Similarly, varan tempers together 6/5 and 13/11. Finally, baragon swaps in a less complex mapping for prime 11, so that [[7/5]] and 11/8 are tempered together.
