Jon E. Schoenfield: "n-digit" appropriately gets a hyphen if it's used as an adjective (e.g., "contains an n-digit palindrome"), but it doesn't get a hyphen in expressions like "palindromes of n digits".

Anton Stefanov: The establishment of a new world record using the method I discovered was the reason for the publication of this sequence and the justification for its importance
