Regarding the encircled numbers, so far as they are independent of 260, I would note the following:—

017 = XIII Akbal to IV Ahau.
121 = XIII Akbal to IV Kan.
196 = III Chicchan to IV Imix.
199 = III Chicchan to VII Kan and XIII Akbal to IV Ik.
235 = III Chicchan to IV Ahau.

In addition let me remark that 36 = VII Kan to IV Ahau, 39 = IV Imix to IV Ahau and 104 = IV Ahau to IV Kan.

The following arrangement will prove that these numbers were as usual also employed to form the large numbers by multiplication:—

17 × 74,620 = 1,268,540 (IV Ahau),
235 × 5,252 = 1,234,220 (IV Ahau),
36 × 42,639 = 1,535,004 (VII Kan),
39 × 32,639 = 1,272,921 (IV Imix),
104 × 12,236 = 1,272,544 (IV Kan).

But the highest number, 1,538,342, was formed in a different way; it = 59,167 × 26; but the interval from IV Ahau to IV Ik = 182 = 7 × 26, and from IV Ik to IV Ahau = 78 = 3 × 26.

If in conclusion, we now examine the twelve numbers of seven figures given in this section, we will clearly see that by twos and twos they plainly belong together in pairs:—

The three pairs of numbers found by computation are as follows:—

1,486,923, XIII Akbal.
1,483,585, III Chicchan.
