from Appendix D Harmonic Numbers in the Mayan Factor, by Jose Arguilles
1, 366, 560 / 9 = 151, 840 = 416 x 365
1, 366, 560 / 12 = 113, 880 = 312 x 365
1, 366, 560 / 13 = 105, 120 = 288 x 365
1, 366, 560 / 72 = 18, 980 = 52 x 365 = 73 x 260
1, 366, 560 / 73 = 18, 720 = 52 x 360 = 72 x 260
1, 366, 560 / 260 = 5, 256
1, 366, 560 / 360 = 3, 796 x 360
1, 366, 560 / 365 = 3, 744 x 365
1, 366, 560 / 584 = 2340
1, 366, 560 / 780 = 1752
1, 366, 560 / 2, 920* = 468
1, 366, 560 / 37, 960** = 36
* 2,920/365 = 8 and 2,920/584 = 5
** 37, 960 = 104 x 365
how these numbers have significance:
260 days = 1 cycle of the sacred calendar = 13 x 20
360 days = 1 Tun = 18 x 20
365 days = 1 Haab = vague solar year (discounting the fraction of a day)
584 days = 1 cycle of Venus (synodic period)
780 days = 1 cycle of Mars (synodic period)
2, 920 days = 1 Solar-Venus cycle = 8 x 365 days = 5 x 584 days
37, 960 days = 36 x 104 years
104 years = 1 conjunction of the sacred calendar, Solar and Venus cycles
