I haven't posted all week but I've been here every day, usually several times per day. Life is super busy. Just a suggestion/reminder for those of you who are using code for this: don't be like me and have tons of commented-out code that you work around. I just thought I'd stumbled on something extremely significant that correlated prime as and bs with a particular pattern but then I looked back at my code and realized the only reason I was only seeing prime as and bs in these places was because the grid was being generated within an if statement that runs if isPrime(a) && isPrime(b), and I didn't see it because of all the commented-out code. It's well past midnight so I could have gone to sleep already if it didn't seem significant. Oh well. Keep on keeping on everybody.
