Shyam Sunder Gupta: "Attribution should be corrected, just use four tildes". What it means?

Shyam Sunder Gupta: a(4) is certified prime. While a(5) is probable prime or certified needs to be confirmed by Giovanni Resta. If it is probable prime, it shall be stated so.

Giovanni Resta: It means that:
(1) in the Extension field you and end the line with "by" or with "from" and the system adds your name and date (the attribution).
(2) in the other fields, and specifically in the Comments, if you write four tildes, i.e., ~~~~, they will be converted automatically into your name and date when you save. So here Joerg is asking you to fix in this way both Comments and Extensions. Anyway, the line in Extension is redundant and can be deleted because you have already your name and date in the Comments. Extension field is for extensions that cannot be signed directly, like if one adds a few terms to the Data field.
