Re: [math-fun] nth digit * nth term

EA: "We start S with a(1) = 2 and always extend S with the product « nth digit x nth term of S ». (When the product is = 0, we don’t extend S with 0 but with the smallest integer not yet present in S.)" See my graph of S to 10^5 here: http://chesswanks.com/num/nthDigit*nthTerm.png Large values in S are created by lengthy non-zero stretches in the digit list, appearing in the graph as spikes that culminate in a peak when the digit is again zero. Based only on the digit list for my calculated S, the peak at a(28385) can be predicted to be superseded by a slightly larger peak at a(350165).
