Notable derivatives of the Cube-series are the 1-solid-gnomons, D = 1, 7, 19, 37, 61, 91, 127, 169, ...
- its terms formed from the differences of adjacent cubes, thus: D(i) = C(i) - C(i-1) = (i)^3 - (i-1)^3 = 3i(i-1) + 1 On Sun, May 22, 2011 at 9:56 PM, Man on Bridges <[email protected]>wrote: > Hi, > > > On 23-5-2011 3:29, Man on Bridges wrote: > >> Hi, >> >> On 18-5-2011 20:05, OrionWorks - Steven V Johnson wrote: >> >>> I didn't immediately know what made mersenne primes so special so I >>> went over to wiki for a qwik upload: >>> >>> http://en.wikipedia.org/wiki/Mersenne_primes >>> >> Nope. >> >> Correct sequence is: 7,19,37,61,91,127,169,217,271,331,397 >> >> Kind regards, >> >> MoB >> > Not to forget the first one being : "1" (i.e. 0 * 6 +1) > > Kind regards, > > MoB > >
