Rich -- turns out Franklin calculated a few terms of the same sequence, about a year ago, which apparently is what led to its becoming A110835 of the OEIS! (At least I can contribute a bunch more terms, in case anyone's interested.) -------------------------- Note: The log_N(k) figure (k is largest registered N-tuple before the first one that's totally composite) seems it may be converging to something around e = 2.718... which seems too weird to be true. As with your 2^N +-3 prime observation, I'll wait till I see a lot more terms, but there's some kind of gestalt definitely emerging. --Dan
