[seqfan] Re: re Integers formed by concatenating primes

[Jonathan Post]

Rather than 1-at-a-time debasification (acid that neutralizes bases?),
I usually suggest giving the main diagonal of the array, and showing
the array, of such a seq parameterized by base k, with row 2 being the
binary seq, row 10 being the decimal seq, and so forth.
