mersenne numbers are the series of numbers which are one less than a power of 2. Mersenne was a 17 cent mathematician monk. Mersenne primes are the subset of mersenne numbers which are prime - the first few being 3, 7, 31, 127 ... 47 of them have been discovered but it may be that there are an infinite number.
There is the photographic secession movement in the early 1900s
Stieglitz: "Yours truly, for the present, and there'll be others when the show opens. The idea of Secession is hateful to Americans - they'll be thinking of the Civil War. I'm not. Photo-Secession actually means a seceding from the accepted idea of what constitutes a photograph."
