• ... that multiple mathematics competitions have asked whether numbers of the form $n^{4}+4^{n}$ can be prime, answered negatively (for $n>1$) using Sophie Germain's identity? Source: Engel 1998, https://books.google.com/books?id=IJLzBwAAQBAJ&pg=PA121

  • Comment: The mathematics formulas cause the usual scripts that calculate readable prose size to miss much of the text of the article: they fail to count any text that follows a block formula within the same paragraph. By my calculations, the readable prose size (not counting formulas, headings, and references) is approximately 2200 bytes.
