Thank you, Franklin -- let's forget this no-name sequence!

While this sequence has fractal-like properties, it is not technically 
a fractal sequence. "Interspersion" is not used loosely as "fractal 
sequence" sometimes is, and is provably equivalent to the technical 
definition of a fractal sequence; so it is certainly not an

Hello SeqFans,

I guess the sequence hereunder is an "interspersion" or a "fractal"
(please correct me):

All [primes minus 1] will appear, of course -- and will be the only
even terms of the sequence; the building process is quite visible.
