[seqfan] Concatenating multiplications and successive results

[Eric Angelini]

Hello SeqFans,

Consider S:

S = 1,11,22,12,24,14,28,18,216,16,212,48,324,312,612,714,416,318,432, ...

This is kind of concatenating multiplications and successive results:

       1x1=1
         1x2=2
         . 2x1=2
         . . 2x2=4
         . . . 4x1=4
         . . . . 4x2=8
         . . . . . 8x1=8
         . . . . . . 8x2=16...

         1 2 1 2 1 2 1
         1 2 2 4 4 8 8

Reading vertically those two last lines, we see S:

    S=11,22,12,24,14,28,18,...
