A Greek textual variant in Revelation 17:3 shows the ambiguity of ancient manuscripts having no spaces between words. This particular variant has caused the Editio Critica Major (ECM) to change its reading away from the NA28 text to that of the Robinson-Pierpont.

And the dots above the letters TA indicate a corrector saying “delete.”)  As for Codex A, it certainly had room for γεμοντα τα ονοματα.  It would make sense in Textual Criticism that when there are two τα in a row, one would get accidentally dropped.
