Back! Star Numbers

Okay, after a break with my other blog (Browser Talk (at BlogOffTheEdge (boardesky@gmail.com))),  I have decided to come back with the Math Blog as a normal blog. However it will not be daily; rather perhaps weekly, and if you're lucky, 2 times a week, and if you're really lucky, 3 times a week.

Never mind. I'm back with star numbers.

Also, I forgot to announce the featured sequence in a post. The "sequence" was not really a sequence, but rather a group of numbers known as Mersenne Primes.

BUT WE ARE NOT HERE TO TALK ABOUT MERSENNE PRIMES!

Star numbers start with 1 (just like almost any other sequence starts with) and expand to a Chinese Checkers board (or Jewish star).

The formula for the nth star number is:

Sn = 6n(n − 1) + 1

So that's the buzz on star numbers, and next up is amicable numbers!
