Equidistant letter sequences (ELS), the Genesis 1:1 arithmetic (2701 = 37 × 73), Panin's heptads, and the scribes who counted every letter: the design under the text, shown as exhibits you can check.

A featured study on this subject, with its Scripture, its sources and its figures.

How Greek counted with its letters, the three lost letters that kept their values, and an honest account of 666: the manuscripts, the 616 variant, Irenaeus, and the Nero argument graded.

The long-form arithmetic behind the Bible codes: Genesis 1:1 letter by letter, the triangular numbers, the heptadic structures: every figure recomputable with a pencil.
