Hi Stephen

Quote 'The difference between 356.5 Ft. and 356.4 is only 1/10th. Ft. or 1.2 ins., so that is a reasonable figure you are using I think.'

Your right it is only 1.2 inches however 356.4 imperial feet is a combination of the numbers 3456 and that is the clue.

356.4 imperial feet = 324 Indus feet (13.2 ins) the perimeter of the third pyramid is 1296 Indus Valley feet a sacred number 1/2 2592 a sacred number 2592. And x 2 = 51.84 the slant angle of the Great Pyramid.

Edwards always took the latest info Petrie measured this pyramid to a step above the core numbers. About 10 feet short but itself an important number.
