Re: Lunisolar Cycle Multiples of Short Lunar Cycle, 5181 years

There is a 5181 year lunisolar cycle with 80 repeats of a 49 yerm cycle

5181 years = [ 2*2*2*2*5 | 2*11827 ] = 64080 months

mean year = 365 & 1255 / 5181 = 365.2422312 days
mean month = 29 & 425 / 801 = 29.53058677 days


5181 years is three of this cycle:
1727 years = 21360 months

5181 years is 334 years less than the 5515 year cycle.

There is also a 8464 year cycle using mean month = 29 & 529 / 997 days but I think anything over a pictun is out of bounds.
