Yes but for numerology to hold true, if the EXACT height of the pyramid was later tested and found to be 1356, it would change "Amphion", and thus,
IF numerology held water,
the relationship between the two should modify both.

Imho it doesn't alter Bo-diddly,
and therefore whatever the true height is really doesn't matter to numerology
because it's all smoke and mirrors anyway...

Jammer
