Since that is not a rule used by anyone who knows what is needed, it is
irrelevant,
A rule that actually works on decimals, or with any base larger than 7,
is to look at the nth digit of the nth element in the list and if it
less than a 6 make the nth digit of the "anti-diagonal a 6 but
otherwise make it a 5.
The the "anti-diagonal" will differ not only with the nth listed element
at its nth digit, it will also differ from any other representation, to
that base, of the same number, Some numbers in any base will have dual
representations so an "antidiagonal" must be designed to avoid both
whenever there are two.
