In these panoramas, a shift of one place toward the right means 12 years later, while a shift of one place downwards gives a conjunction 83 years later.

In the case of Jupiter-Regulus, after 2, 3 or 4 'duets' of TCs (such as 1612-1624) we have the start of a new vertical series (for instance 1719), where one or two 'triplets' of TCs take place (1695-1707-1719 and 1778-1790-1802). Each vertical, 83-year series contains 10 or 11 TCs and lasts for about eight centuries.

In the case of the Jupiter-Aldebaran, the vertical series contain only nine TCs, and for this reason the triplets are much rarer than for Regulus. Between the years 0 and 2100 there is only one triplet of TCs Jupiter-Aldebaran (in 624-636-648), while there are nine for Regulus. This difference is due to the eccentricity of the orbit of Jupiter. In the constellation Taurus, Jupiter is closer to its perihelion, in Leo it is closer to the aphelion.

Triple conjunctions of Mars and a given star too can be grouped in a panorama, in such a way that they are arranged vertically in 79-year series, and horizontally in 363-year series. One gets an interesting view when the panorama is drawn as in Figure 41./, where every thick dot represents a TC. Only for the points situated between the upper and lower solid lines is there a TC. In A.D. 1006, for instance, represented by the small dot just above '1085', no TC occurred between Mars and Antares. See also Figure 41.g.
