Why this pyramid belongs in the collection
Meidum links the step-pyramid tradition to the true pyramid and belongs in any famous-pyramid sequence. Its current tower-like core also demonstrates how far a surviving appearance can sit from the intended final geometry.
What can be measured
UCL Digital Egypt publishes representative measurements of 144 metres for the base and 92 metres for the height. The calculator treats these as a final smooth-pyramid reconstruction, producing a face angle near 52 degrees and slant near 116.82 metres.
The native or comparative measure
The calculated seked is about 5.48 palms per cubit of rise. Because the metre inputs are rounded, the result should not be mistaken for an exact recovered palm fraction.
The pattern worth testing
Both the perimeter-to-height and slant-to-half-base tests pass the declared tolerance for 2 pi and phi. This resembles Khufu, but the rounded reconstruction makes the result particularly sensitive to which dimensions are selected.
Interpretive limit
A close result derived from rounded reconstructed dimensions is an invitation to inspect the source, not a proof of a lost constant. The sequence of building stages is better attested than any esoteric interpretation.
A repeatable investigation
Begin with the published or reconstructed dimensions and state the shape assumption. Calculate the seked and ordinary geometry before testing a named constant. Keep the chosen broad ±0.5 exploratory screen fixed across the full collection, display the residual for every match, and treat a numerical result as evidence of intention only when independent historical evidence supports it.
