EXAMPLE

There are no (LynchBell) numbers with zero digits.
The nine onedigit LynchBell numbers are {1, ..., 9}.
The five twodigit LynchBell numbers are {12, 15, 24, 36, 48}.
The sevendigit LynchBell numbers are 105 permutations of (the digits of) 9867312, which is the largest possible LynchBell number. (The digit 5 cannot appear since there is at least one even digit. Replacing any of the given 7 digits by a digit 4 yields numbers not divisible by 9, or not divisible by 3 if the 9 is replaced.)
