COMMENTS

If we are ever going to understand A268236 then we need to understand this sequence first.
Based on Nathan Fox's extended table in A268236.
Equivalently, numbers 4k (k>5) whose representations in bases 5 through k2 each contain at most one 4.
Equivalently, numbers 4k (k>5) whose representations in integer bases less than sqrt(4k) each contain at most one 4.
Is this sequence infinite?
