Numbers are given in compact notation 6(n) where n is the number of 1's that follow the digit 6. For example, 61111111 would be written 6(7). All prime factors are listed. Factors with the notation (probable prime) are not proven prime. Numbers in square bracket preceeded by "Cn" are unresolved composite factors. Entries in red are not completely factored, or have factors not proven prime.
