Thank you Neil NJAS, seqfans,
(on-line encyc of Integer sequences.)
(Tony test. greeting)

For future reference [f.a.q.] these (puzzles) should be tackled-

How did you get those numbers?
1*2*34*44432+1 is easier to remember than 36-th Mersenne prime.

What is the formula, program, calculation steps.
where did they come from?

Is it a silly IQ test?
What are your thoughts on solving it..?
