Actually, I think the def'n is the same as A105441, not A093642.
... 55 doesn't belong to "our" array -- but is in A105441. I must have misunderstood your def'n, or I am making some obvious arithmetic error; I thought your sequence was all numbers that were left out of the array --- in other words, all numbers not of the form 2^n*p_j, where p_j was prime. 55 is not a prime, nor is it 2^n times a prime so I thought it wasn't in your sequence. What is the correct definition of your sequence?
