There are two natural points from which to begin counting, viz. at the beginning of the text (Ga1-1) or at Ga1-26. In the latter case we should probably count from Gb1-6 as regards Gb5-25.

	24		208		235
Ga1-1		Ga1-26		Gb1-6		Gb8-30

The results show how closely Ga7-19 and Gb5-25 are connected numerically regarded:

Ga1-1	1	Ga1-1	1	Ga1-26	1	Gb1-6	1
Ga7-19	188	Gb5-25	378	Ga7-19	164	Gb5-25	144
188 = 4 * 47		378 = 9 * 42		164 = 4 * 41		144 = 4 * 36

188 is very close to 190 (= 378 - 188), i.e. Gb5-25 is about twice the distance from Ga1-1.
